Oh, one of *those*... ;-)

I generally just don't code anything at that hour. It never ****ing 
works right anyway.

Heh, well, I did wonder. Actually, as I say, I just assumed that since 
it was *so* wrong, you must already know about it but just haven't got 
round to fixing it yet.

Pah. Mutable state is evil! ;-)

Very, very slowly. Like, I'm having trouble making it so that I can add 
and remove wires and stuff efficiently and still be able to look up what 
connects to what efficiently and...

(See my post about "highly redundant data structures.)

You, by comparison, have got something that *runs*. I'm still faffing 
around with design choices.
