There's never a need to use 'while' either, given there's a plethora of other good flow control structures as well. But from that doesn't follow we should shy away from 'while'. Perl gives the programmer a full toolbox, full enough to make almost any tool 'redundant', in the sense that there are enough other tools to not use a particular tool. But we don't use that argument to select some tools, and reject others.

Personally, I use almost every tool* in the toolbox. Some more than others. I don't use goto often, but I do use it. For instance, in code like this:

my $max_tries = 10; GETSTORE: my $url = ask_url(); my $status = getstore($url, $file); goto GETSTORE if $status == 200 && !-s $file && --$max_tries > 0; ... do stuff ... return $status;
I find that more attractive than
my $max_tries = 10; my $status; { my $url = ask_url(); $status = getstore($url, $file); redo if $status == 200 && !-s $file && --$max_tries > 0; } .. do stuff .. return $status

*Tools I never use that I can think of right now: formats, 1-arg open, study, and /o.
