So "complete recursive expansion" is postwalk macroexpansion? It seems
like that could break anaphoric macros, and likely others. A macro has
the option of calling macroexpand-all on its own contents if it wants
only special forms, but it shouldn't be forced to take only special forms.
Recursive macro expansion still works from outside in, so each macro gets
to see the unexpanded form. It's only after the macro has done its
transformation that the inner forms get expanded.
Also, here's a sketch of how you could do symbol macros using
Riddley: https://gist.github.com/ztellman/6439318. Please let me know
if I'm missing something w.r.t. how symbol macros are done in
tools.macros.
It's on my reading list for tomorrow!
Konrad.
