Re: changing array size in foreach loop: is it safe?

I think a clean and clear way to do this is with a while loop, maintaining your own index. Something like this:

my $i = 0;
while ($i <= $#foo)
{
    push @foo, 'h' if $foo[$i] eq 'd';
    print $foo[$i];
    $i++;
}

It occurred to me that in my real code I don't actually need the value of @foo afterwards, so I should just use shift: `while (@foo) { my $x = shift @foo; push @foo, 'h' if whatever(); }` [download]	[reply] [d/l]
