From the keyboard of sondeen@venera.isi.edu (Jeff Sondeen):
:
:The following works without the caret (^) specifying beginning of line; with
:the caret, it doesn't match the input (which starts in column 1):
:
:program:	perl -ne 'if (/^\w:/) { print; }'
:on input:	nope:
:gives result:	<nothing>
:expected result: nope:
:hypothesis:	the caret(^) specifying beginning of line is messing up the
:		regular expression matching
:version:	This is perl, version 3.0 ... Patch level: 44

Not sure how that's a bug: /\w/ doesn't mean /\w+/, so /^\w/ can 
be expected to fail on "nope:".
