Regexp::Common::whitespace -- provides a regex for leading or trailing whitescape
use Regexp::Common qw /whitespace/;
while (<>) {
s/$RE{ws}{crop}//g; # Delete surrounding whitespace
}
Please consult the manual of the Regexp::Common manpage for a general description of the works of this interface.
Do not use this module directly, but load it via Regexp::Common.
$RE{ws}{crop}Returns a pattern that identifies leading or trailing whitespace.
For example:
$str =~ s/$RE{ws}{crop}//g; # Delete surrounding whitespace
The call:
$RE{ws}{crop}->subs($str);
is optimized (but probably still slower than doing the s///g explicitly).
This pattern does not capture under -keep.

Curse the idiot(s) who think that version numbers are floats (in which universe do floats have more than one decimal dot?). Everything is bumped to version 2.100 because CPAN couldn't deal with the fact one file had version 1.10.

Bound to be plenty.
For a start, there are many common regexes missing. Send them in to regexp-common@abigail.nl.
