Generation time optimization with sbcl

[lispbub]

Code generation time can be heavily increased via (setf sb-ext::*evaluator-mode* :interpret) but that breaks when (let (..) ) definitions are used for code substitution.
Performance increase seems plausible: no compilation, no optimization ...
Investigate what is wrong, and set this mode as default?

I just ran into this and added the following to my Makefile.am:

CM = cm c++ -E '(setf sb-ext::*evaluator-mode* :interpret)' 

Instant performance boost :)
