Not in connection with any one issue in particular, I'm trying to make the compiler re-entrant.
That ought to be a sufficient remedy to this, right?

I wonder if we can play with compute-applicable-method to force
compilation of the interfaces/implementations ahead of time?
<https://github.com/guicho271828/inlined-generic-function> might hold
some tips on how to do that. This might a fun project if you'd like to
explore the MOP.

Martin's idea is promising too.

Regarding your patch, I really dislike defining special variables
without the earmuffs. I've been bitten by such variables in the past
and it's quite annoying and confusing. (defconstant would be slightly
better, but still I'd rather pursue the other two ideas first. :-(
