Hmm, but aren't the .go files the compiled files?  I've removed those before 
testing.  And the guix script has "--no-auto-compile". I don't really 
understand this part yet...

The idea was that it would load the module just in time when the procedure is 
executed.  In any case, module-ref can't hurt either, so that's in master now.

It does.  I think the state in master now is good and we can review the 
remainder at our leisure and I can stop hot-fixing things now.  Phiew... :)

Yeah...

True, it's okay.

Though, it would be nice if there was a way to run the interpreted version 
locally - without it taking several hours each time.  Would it be possible for 
guile to have some static analysis that catches these things?  Doesn't seem 
that difficult: Just walk the modules, remember when you see record 
definitions, remember when you see record usage.  In fact I'll write a 
throwaway script to do just that for next time.  (I've already got my Makefile 
generator to find Guile module cycles :) )
