in thread recursive anonymous subroutines

Just thought I'd point out that this is an interesting reinvention of a previous post (though with one less level into the call stack due to the goto). Compare:
# Your's: sub make_call { goto $_[0] } # Anonymonk's(slightly rearranged): sub Y { $_[0]->(@_) }
Update: Well, it's more the same if you change your call to:
make_call (sub { my $factor = $_[1]; return $factor > 1 ? $_[0]->($_[0], $factor-1) * $factor : 1; }, $_);
