Re: Re: is the use of map in a void context deprecated ?

...I seem to recall that map was just rewritten to check for void context and avoid the extra work if possible.

That is correct. And it's in Perl 5.8.1! From the 5.8.1. perldelta:

"map" in void context is no longer expensive. "map" is now context aware, and will not construct a list if called in void context.

It's just a source filter though, and while it tries really hard to parse Perl, only `perl` really can. F.ex, I (only accidentally) discovered it was causing a spurious problem for someone else a while ago that seemed to be completely unrelated. Makeshifts last the longest.	[reply]
