Could someone please tell me how to define brackets ("[", "]") as
macro characters in CommonLisp so that they have the same effect as
the usual parens (but make for more readable code)? 

E.g., (let ([x 2]) (+ x x)) should parse as (let ((x 2)) (+ x x)).

Since this is about the only place where I'll ever (?) have to mess
with tricky readmacros, and the chapter on Input/Output in CLtL is way
too humongous right now, I request indulgence for not figuring it out
for myself.

Email would be divine.
