Re^2: returning to a loop later on

redo FILENAME doesn't have a matching loop.
it doesn't have to be a loop, you can label blocks, too!

my $i = 0;
FOO: {
    print "$i\n";
    redo FOO unless ++$i > 4;
}

Indeed, but you can't redo to a label that is not in labling the current scope: `FOO: { # scope 1 { # scope 2 redo FOO; # Ok } redo FOO; # Ok } { # scope 3 redo FOO; # Illegal }` [download] Prints: DWIM is Perl's answer to Gödel	[reply] [d/l] [select]

you can't do that with a loop, either, right? perhaps i am misunderstanding you, but that is not the situation with the OP's code, imperfect as it may be; the `redo FILENAME` is within the `FILENAME: { }`	[reply] [d/l] [select]

My appologies. OP's code, as you say, is not like that. I was confused by indentation issues :(. DWIM is Perl's answer to Gödel	[reply]
