Language::Befunge::Debug - optimized debug solution for language::befunge

    use Language::Befunge::Debug;
    debug("foo\n");     # does nothing by default
    Language::Befunge::Debug::enable();
    debug("bar\n");     # now that debug is enabled, output on STDERR
    Language::Befunge::Debug::disable();
    debug("baz\n");     # sorry dave, back to no output

This module provides a debug() subroutine, which output on STDERR if debugging is enabled. If debugging is disabled (the default), perl will optimize out those debugging calls.

The module is exporting only one function:

* debug( @stuff );

If debugging is enabled (which is not the default), write @stuff on STDERR.

The module also provides 2 functions to control debugging:

* Language::Befunge::Debug::enable();

Request that calls to debug() really start output on STDERR.

* Language::Befunge::Debug::disable();

Request that calls to debug() stop output-ing on STDERR.
