Hi Matt!

Find small bugfix for GOTO attached.

I'm making some progress with Mescc.  The compiler layout starts to make
some sense now and after getting function calls and parameters in place
and many special cases for call/if/for/when it seems that I finally have
an idea that works for handling tests and expressions.

So, now I'm starting list of tests that uses goto, which i'll need
anyway for the core evaluator.

Greetings,
Jan.
