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

-(F) It used to be that Perl would try to guess whether you wanted an
-array interpolated or a literal @. It did this when the string was
-first used at runtime. Now strings are parsed at compile time, and
-ambiguous instances of @ must be disambiguated, either by prepending a
-backslash to indicate a literal, or by declaring (or using) the array
-within the program before the string (lexically). (I<Someday it will
-simply assume that an unbackslashed @ interpolates an array.>)
