I was actually copy-pasting the function from Emacs to OpenMCL running
in the terminal. Just to be sure, I did COMPILE:
? (compile 'decode-next-letter)
OpenMCL is a compiler only implementation AFAIK, so function
definitions are all compiled anyway.
SLIME or Swank (perhaps the swank-openmcl backend) are definitely doing
something to make this take a long time. I just have no idea how to
figure out what. If +letter-frequency-hypercube+ is being expanded
into a temp file, that would certainly be very suspect. If it's just
the symbol, then I'm barking in the wrong direction.
The dfsl file that holds the definition to +letter-frequency-hypercube+
is about 12MB.
