1265 \d is a digit and represents [0-9], \s is a whitespace character and
1266 represents [\ \t\r\n\f], \w is a word character (alphanumeric or _) and
1267 represents [0-9a-zA-Z_], \D is a negated \d; it represents any character
1268 but a digit [^0-9], \S is a negated \s; it represents any non-whitespace
1269 character [^\s], \W is a negated \w; it represents any non-word character
1270 [^\w], The period '.' matches any character but "\n", no modifiers (//):
1271 Default behavior. C<'.'> matches any character except C<"\n">. C<^>
1272 matches only at the beginning of the string and C<$> matches only at the
1273 end or before a newline at the end, s modifier (//s): Treat string as a
1274 single long line. C<'.'> matches any character, even C<"\n">. C<^>
1275 matches only at the beginning of the string and C<$> matches only at the
1276 end or before a newline at the end, m modifier (//m): Treat string as a set
1277 of multiple lines. C<'.'> matches any character except C<"\n">. C<^> and
1278 C<$> are able to match at the start or end of I<any> line within the
1279 string, both s and m modifiers (//sm): Treat string as a single long line,
1280 but detect multiple lines. C<'.'> matches any character, even C<"\n">.
1281 C<^> and C<$>, however, are able to match at the start or end of I<any>
1282 line within the string
1284 =item Matching this or that
1286 =item Grouping things and hierarchical matching
1288 0 Start with the first letter in the string 'a', 1 Try the first
1289 alternative in the first group 'abd', 2 Match 'a' followed by 'b'. So far
1290 so good, 3 'd' in the regexp doesn't match 'c' in the string - a dead end.
1291 So backtrack two characters and pick the second alternative in the first
1292 group 'abc', 4 Match 'a' followed by 'b' followed by 'c'. We are on a roll
1293 and have satisfied the first group. Set $1 to 'abc', 5 Move on to the
1294 second group and pick the first alternative 'df', 6 Match the 'd', 7 'f' in
1295 the regexp doesn't match 'e' in the string, so a dead end. Backtrack one
1296 character and pick the second alternative in the second group 'd', 8 'd'
1297 matches. The second grouping is satisfied, so set $2 to 'd', 9 We are at
1298 the end of the regexp, so we are done! We have matched 'abcd' out of the
1301 =item Extracting matches
1303 =item Matching repetitions
1305 C<a?> = match 'a' 1 or 0 times, C<a*> = match 'a' 0 or more times, i.e.,
1306 any number of times, C<a+> = match 'a' 1 or more times, i.e., at least
1307 once, C<a{n,m}> = match at least C<n> times, but not more than C<m> times,
1308 C<a{n,}> = match at least C<n> or more times, C<a{n}> = match exactly C<n>
1309 times, Principle 0: Taken as a whole, any regexp will be matched at the
1310 earliest possible position in the string, Principle 1: In an alternation
1311 C<a|b|c...>, the leftmost alternative that allows a match for the whole
1312 regexp will be the one used, Principle 2: The maximal matching quantifiers
1313 C<?>, C<*>, C<+> and C<{n,m}> will in general match as much of the string
1314 as possible while still allowing the whole regexp to match, Principle 3: If
1315 there are two or more elements in a regexp, the leftmost greedy quantifier,
1316 if any, will match as much of the string as possible while still allowing
1317 the whole regexp to match. The next leftmost greedy quantifier, if any,
1318 will try to match as much of the string remaining available to it as
1319 possible, while still allowing the whole regexp to match. And so on, until
1320 all the regexp elements are satisfied, C<a??> = match 'a' 0 or 1 times. Try
1321 0 first, then 1, C<a*?> = match 'a' 0 or more times, i.e., any number of
1322 times, but as few times as possible, C<a+?> = match 'a' 1 or more times,
1323 i.e., at least once, but as few times as possible, C<a{n,m}?> = match at
1324 least C<n> times, not more than C<m> times, as few times as possible,
1325 C<a{n,}?> = match at least C<n> times, but as few times as possible,
1326 C<a{n}?> = match exactly C<n> times. Because we match exactly C<n> times,
1327 C<a{n}?> is equivalent to C<a{n}> and is just there for notational
1328 consistency, Principle 3: If there are two or more elements in a regexp,
1329 the leftmost greedy (non-greedy) quantifier, if any, will match as much
1330 (little) of the string as possible while still allowing the whole regexp to
1331 match. The next leftmost greedy (non-greedy) quantifier, if any, will try
1332 to match as much (little) of the string remaining available to it as
1333 possible, while still allowing the whole regexp to match. And so on, until
1334 all the regexp elements are satisfied, 0 Start with the first letter in the
1335 string 't', 1 The first quantifier '.*' starts out by matching the whole
1336 string 'the cat in the hat', 2 'a' in the regexp element 'at' doesn't match
1337 the end of the string. Backtrack one character, 3 'a' in the regexp
1338 element 'at' still doesn't match the last letter of the string 't', so
1339 backtrack one more character, 4 Now we can match the 'a' and the 't', 5
1340 Move on to the third element '.*'. Since we are at the end of the string
1341 and '.*' can match 0 times, assign it the empty string, 6 We are done!

4722 sort() has been changed to use mergesort internally as opposed to the
4723 earlier quicksort. For very small lists this may result in slightly slower
4724 sorting times, but in general the speedup should be at least 20%.
4725 Additional bonuses are that the worst case behaviour of sort() is now
4726 better (in computer science terms it now runs in time O(N log N), as
4727 opposed to quicksort's Theta(N**2) worst-case run time behaviour), and that
4728 sort() is now stable (meaning that elements with identical keys will stay
4729 ordered as they were before the sort)
