I was going to open a feature request bug for a function to
specifically expand compiler-macros, but if the behavior reported here
is intended, then I don't really need to.
However, if this is the intended behavior of macroexpand-all, it is
inconsistent with the documentation, which says:
=E2=80=98macroexpand-all=E2=80=99 expands macros like =E2=80=98macroex=
pand=E2=80=99, but will look
for and expand all macros in FORM, not just at the top-level. If
no macros are expanded, the return value is =E2=80=98eq=E2=80=99 to FO=
RM.
But macroexpand is defined in C source code, and definitely *only*
expands function symbols whose value has a car of 'macro.
Could someone determine if this is a bug in macroexpand-all (e.g. it
should be checking whether it is being called while byte-compiling),
or just a documentation bug?
Thanks,
Lynn

And macroexpand-all seems to be closely tied to the compiler, or the other way round, depending on one's perspective. I personally find that behavior a bit surprising, but that's just me.
