    Does it make sense for nested lambda lists in a defmacro to contain things
    like &environment?

No, it doesn't make sense.  There is only one environment (the one in
which the macro is being expanded in).  (Nor can it be destructured.)

    CLtL does not say whether the non-top-level lambda lists
    should be ordinary function lambda lists or whether they can use the extended
    syntax.

I almost couldn't find &environment because of a "publishing" glitch!!
The last paragraph on page 145 is supposed to have &environment next to
it, but doesn't.  Indeed, the spec should be explicit about what may
appear in nested lambda lists.
