Hi every 1
I know this sound like a mostly theoretical "I wondered" question,
but I actually got a practical reason (long to explain) to ask this:
is there a value of $reg which will return true by
$emp =~ /$reg/;
when and only when $emp is an empty string ?
Thx
Update:
My personal definition of an empty string is zero-length.
Technically it doesn't include undef, as it isn't a string, but its irrelevant for my use.
Update: problem resolved.
It seems to me that ^\z and \A\z function the same way,
but as \z seems better than $ for this purposeת>נר<
I'll assume the same for their counterparts and go with \A\z over ^\z.
(unless one of you will find another loophole ^^)
But regardless thanks all around :]
