Hmm, I should really clean up and commit the patch sometime. I went with deftype and coerce instead, and would feel extremely uneasy committing ccl::anything anywhere outside CCL itself.

After talking with Gary Byers about it, I ended up with the following function (which should probably be a macro but whatever): (defun PLATFORM-FLOAT (value) #+32-bit-target (ccl::float value) #+64-bit-target (ccl::%double-float value)) Now I use (platform-float abc) to coerce to the right type for calling CoreGraphics, OpenGL, and other Mac OS calls.
