Well, I knew I'd forgotten to tell Number::Tolerant to require 5.6, which it wants. (I like warnings and our, and I'm willing to require 5.6 for them. It's old!) Now I realize it needs 5.8, too, due to this weird bug:
use strict;
use warnings;
package Noval;
use overload fallback => 1, '0+' => sub { undef };
package main;
my $noval = bless {} => 'Noval';
my $plus0 = 0 + $noval;
It segfaults 5.6, and I just don't care enough to investigate deeply. We use 5.8 at work, after all.
