[implementations-list] Why can't I byte-compile (all of) Vimpulse?

You're right, it isn't. Phew! I can't tell you how relieved that makes
me. :)

On closer inspection, `defvar' statements in the compiled file are
indeed recognized by the compiler (even if they are part of macro
expansions), but they aren't evaluated. So if you have a macro which
depends on the /value/ of a same-file variable to produce its
expansion, you do need to use `eval-and-compile'. (Vimpulse doesn't
have this, but the test code I wrote did.)

Anyway, I moved all variable definitions to vimpulse-dependencies.el
in commit [c757a0e4ff], and that helped things immensely.

Thanks for this! Added in commit [701ac452c9].
