Hmm... yes ... interesting ... I see the problem: byte-compile-function-put
receives a form that's been preprocessed.  These look very much like
Elisp, but fundamentally, they're really just a different intermediate
representation, which includes things like `internal-make-closure', so
they can't be used as Elisp expressions (e.g. passed to `eval`): they
need to be passed through the rest of the compiler before they can be used.

I'm not sure yet how best way to solve this.
