Re^2: looking for a good idiom: return this if this is true

in thread looking for a good idiom: return this if this is true

Hardly a deficiancy... especially when return; doesn't return undef _OR_ (), it returns both undef _AND_ () at the same time (dependending on context of course).

We would have to replace all existing return; with return wantarray ? () : undef;

ugh...

It returns the equivalent of an empty list, which in a scalar context, is undef. `my $x = ();` [download] Sets $x to undef. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply] [d/l]
