( #3333=superdoc: print w/replies, xml ) Need Help??
Perl foreach seems to have its own scope created for each loop and then the closure snaps the current scope. The following, code without the foreach code does 444,
my $i; $i = 0; push(@flist, sub {$i * $_[0]}); $i = 1; push(@flist, sub {$i * $_[0]}); $i = 2; push(@flist, sub {$i * $_[0]});
Python must behave this way, no per loop scope. But it let me ask myself (and the monks in fact) why the following code does 024?
my $i; foreach $i (0 .. 2) { push(@flist, sub {$i * $_[0]}); }
Does not my define the scope and then putting it before the loop should not make it apply on the loop? Note: lisp can behave both ways, and maybe even more, one may not compare lisp with javascript:)
