matching a null string) will split the value of EXPR into separate
characters at each point it matches that way. For example:
- print join(':', split(/ */, 'hi there'));
+ print join(':', split(/ */, 'hi there')), "\n";
produces the output 'h:i:t:h:e:r:e'.
of C<//> to mean "the last successful pattern match". So, for C<split>,
the following:
- print join(':', split(//, 'hi there'));
+ print join(':', split(//, 'hi there')), "\n";
produces the output 'h:i: :t:h:e:r:e'.
when LIMIT is given and is not 0), regardless of the length of the match.
For example:
- print join(':', split(//, 'hi there!', -1));
- print join(':', split(/\W/, 'hi there!', -1));
+ print join(':', split(//, 'hi there!', -1)), "\n";
+ print join(':', split(/\W/, 'hi there!', -1)), "\n";
produce the output 'h:i: :t:h:e:r:e:!:' and 'hi:there:', respectively,
both with an empty trailing field.
