Aha cl-lib.el, ok, ok could be worse... I'd thought of adding my own
to yasnippet, but this is nicer of course.

Could, but not likely. I've barely time to fix yasnippet bugs, I'd
rather forward this to Roland Walker, who's been contributing the
yasnippet compatibility fixes. He might want to help, just have to ask
his email, is he on this list?

Agree. But don't forget that some of the weirdness might be in
use by libraries. Yasnippet, as I inherited it, uses that dynamically
and globablly fsetting behaviour to mock functions. Not a big deal to
change, but there might be other libraries that do.

So to summarize: there is going to be a forward compat lib, 'labels'
and 'dolist' and 'mapcar' and such are still valid for some time to
come. 'flet' is going away now, and 'cl-flet' will provide the same
weird behaviour with a nicer implementation.

Thanks!
