Sorry that I still haven't had a chance to look at your code or even
play with it.

I find the :typed and :typed-no-xep hard to remember, though.  Could it
be :unboxed instead?  That makes it pretty clear that you're using
calling convention that supports unboxed args.

Also, how complex is it to keep track of this information so that the
compiler can make the appropriate call?

Oh, and is there a use case you're interested in where block compilation
doesn't do what you want?  (In my particular, hypothetical use case, I
can see doing this with f2cl'ed code where the preferred technique is
putting one Fortran function per file.  But this seems to rather
uncommon but would be very useful.)
