Why use the goto at all? A do while loop does the same thing nicely. 

use strict;
use warnings;

test1();

sub test1 {
    while () {
        my $v = 0;
        next if $v = get_true();
    }
}
sub get_true { 1 }

My question comes as a result of a lifetime of being told to avoid goto--it's considered harmful, after all.

I've seen this pattern of recursion via goto() show up here a few times and I am interested in the pros and cons of this technique.

Now, I can see the harm in abusing goto, but IMO the original code hardly counts as abuse. How does the OP's code behave differently than my while loop? Are there any significant differences that would make the decision to use one approach or the other anything but stylistic choice?
