Sounds good.  If someone wants to look deeper into what it would take to
use ECL in Emacs, that would be very welcome.

There are lots of potential issues in such a project.
A start would be to check:
- does it use its own event loop?
- can it handle conservative stack scanning?
- what other conventions are needed for C code to cooperate with the GC?
- could we do something akin to our "dump"?

Of course, another issue with Common-Lisp integration is that we'd want
to figure out how to integrate the two languages.  So, we'd need to
investigate what are the current incompatibilities.
