Still thinking about it. The problem with doing that is the cleanup of local environments when you have premature exit. If I can resolve that in a clean way I'll of course include those two.

However, it certainly isn't hard to use strings to change programs to lists and vice versa, and I currently have a newRPL program that does just that. (Also one to change regular programs to immediate ones.)

Not having to constantly type << EVAL >> MAP, on the other hand, to say nothing of AXL << EVAL >> MAP AXL, may have saved me from carpal tunnel.

If you need to run a list as a program, you can still do it, but now you need:
<< XEQ >> MAP
sounds familiar?
But don't get your hopes up, all the loop and control structures, cannot be executed by XEQ (will do nothing), as they need a proper run stream. However, stack based commands work fine, like IFT, IFTE, etc.
In any case, I don't think self-modifying code masqueraded as lists is a very good programming technique.

EDIT: Forgot to mention, all roms were updated with latest bugfixes. See the first post.
