Macros are expanded prior to Babel code evaluation=E2=80=94they can make ni=
ce
shortcuts for long Babel calls=E2=80=94so they have to obey to the same rul=
es as
Babel code evaluation, which ignores ":noexport:" directive. I do
realize that macros, however, are expanded within commented trees; this
is a mistake I am going to fix.

Of course, if we accept to limit more macro expansion scope, we get more
latitude in choosing the position of the expansion stage during the
export process. I'm open to discussions about it, and more generally,
about macros' features.

Regards,
