I don’t know if this has been requested, but…
Any interest in defining (lisp-implementation-type) to return “uLisp” (or something similar)?
I’m writing some reasonably simple code (in the uLisp Common Lisp subset) that I would like to run on both an MCU (uLisp) and desktop (SBCL, CCL, LispWorks, etc) and know what platform it is running on.
