Look through the comp.compilers archives.  This kind of thing was done
in the 1970's.  Current beliefs are, apparently, that this is Not Good.

If you're gonna provide macros, then use macros for everything, throw
away all of the current syntax (rather, rewrite it in terms of the macros)
and use a single notation throughout.

Do macros really provide that much more than functions + es's quoting
rules + eval?  I dunno.  I do know that I'd hate to see defmacro and , and
` without good reason.
