You can use `macroexp-let2' for that (with the extra benefit that it
will skip the `let' if `alist' is already a trivial expression such as
a simple variable).

Thanks, I didn't about that. Unfortunately, it seems to not be
available on 24.2 or earlier. (at least, I couldn't find it)
I want to develop this version in parallel with the Elpa version for
now, while there are still a couple of features I'm planning to add.
But I'll add it in later (before release).
