Dunno why I thought that was ever a good idea. It's irregular, and also will be slower since the full call instructions cons in our dumb VM implementations.
for cleanliness
The Clasp implementation already does this and has acceptable compilation overhead, and makes it easier to do further compilation. Plus it's just nice. Makes things a lot easier to debug.
Needs tests and needs to work in FASLs, but the basic structure is in place now.
Yuck, but it's something, and helped me fix a few bugs.
Not including syntax problems yet.
This probably slows things down a little bit, but it has an important advantage: assuming the host Lisp is decent, it can keep enough information that the bytecode module and current IP can be extracted from a host frame. And with that you can get source info and whatever else. I wrote a proof of concept of this in SBCL, but you need to use undocumented/fragile internals, so I won't be including it in Maclina at least for the moment.

Starts on instruction-mapped info in the form of source locations.
Very incomplete: in particular there is no FASL support (i.e. FASLs dump fine but lack source info).
