Well, the author of the closure conversion code (cconv.el) picked a few
files and "made them use lexbind" (mostly set lexical-binding to t and
replace lexical-let by let), among them pcase and mpc.  Since compiling
uses pcase (via macroexpand-all), running the compiled mpc code is
a good test (also the mpc code used lexical-let to build closures).

I.e. running mpc.el was my first "non-toy test" and it bumped into
a good number of bugs.  So, while I'm sure there are still bugs lurking,
I expect that most codes should be compiled correctly now.
