Re^7: To initialise or not to initialise?

[runrig]

When you loop over a list, the local variable is aliased to each member of the list.

Yes, I got that part. The part that surprises me is that B::Deparse deparses it to something that doesn't work, and I always assumed that the deparsing was correct. Consider:

use strict;
use warnings;
foreach $_ (my ($foo, $bar, $baz)) {
  $_ = "default";
}
print "$foo\n";

This code doesn't run, and it is what I mistakenly assumed your code was the equivalent of (minus the use's and print).

Ah. Because it scopes the variables differently depending on whether the loop is inline or not.

Isn't that the definition of a bug in B::Deparse then?

I wanted to file a bug report, but rt.cpan.org doesn't know about 'B::Deparse'. Where should it be sent to? Or did you do that already?

[runrig]

B::Deparse is a core module, so it would go to p5p (or to PerlBug via perlbug). If you want to submit a bug report, search the p5p archives first (or bugs.perl.org), and I'm not sure if B::Deparse is suppose to guarantee perfectly accurate code.

Thanks, I searched and found something similar, though not the same.

Therefore I filed a new bug via perlbug, got ID #30504.
