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.
