Your notion of the correct use of macros seems to be a religious idea rather than one fully thought through. You justify it with circular reasoning. Whilst using a macro to generate an evalable form may be the most usual thing, there is no reason not to use it to produce other list structure.
Except that such macros can only be executed in a particular context i.e. they depend on something that cannot be expressed via their argument list. At best that is poor style, and at worst it is poor engineering. -- Kevin Rodgers Denver, Colorado, USA
