NAME

Goto::Cached - a fast drop-in replacement for Perl's O(n) goto

SYNOPSIS

sub factorial($) {
    use Goto::Cached;
    my $n = shift;
    my $accum = 1;

    iter: return $accum if ($n < 2);
    $accum *= $n;
    --$n;
    goto iter;
}

DESCRIPTION

Goto::Cached provides a fast, lexically-scoped drop-in replacement for Perl's builtin goto. Its use is the same as the builtin. goto &sub and jumps out of the current scope are not cached.
