NAME

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

SYNOPSIS

use Goto::Cached;

my $label = 'LABEL3';

goto LABEL1;

LABEL1: goto $label;

LABEL2: print "Not reached!", $/;

LABEL3: print "label3!", $/;

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.

In a simple benchmark (see t/benchmark.t), static gotos are approximately 6 times faster than the builtin, and dynamic gotos are approximately 1.6 times faster.
