Re^2: non aliased default var $

Thanx, my $_ = $_; is really a good idiom!

In this example with map it might look complicated, because we have to define a return value...

...but in a for loop it's easy to spot, understand and handy to use.

Perfect! :)

from perlsub The fix is to add local(): `local $_ = 5`; ... As of perl 5.9.1, you can now use a lexical version of $_ by declaring it in a file or in a block with "my". Cheers Rolf	[reply] [d/l]
