Issue: DEFMACRO-LAMBDA-LIST, v.2

[Richard Mlynarik <Mly@AI.AI.MIT.EDU>]

      1. a. Specify that &BODY may appear at any level of a DEFMACRO lambda list.

	 b. Specify that &WHOLE may only appear at any level of a DEFMACRO
	    lambda list. At inner levels, the &WHOLE variable is bound to

``May only appear at any level'' sounds like a control-Y bug.

	 c. Specify that &ENVIRONMENT may only appear at the top level of a
	    DEFMACRO lambda list.

Something else which needs to be clarified is where the &ENVIRONMENT
keyword may appear.

Which of the following are legal?

1. (defmacro foo (&whole w &environment e a b) ...)
2. (defmacro foo (&environment e &whole w a b) ...)
3. (defmacro foo (&whole w a b &environment e) ...)
4. (defmacro foo (&whole w a &environment e b) ...)

I'd like to say 1,2 and 3 only, even though case 2 would require some
modification of the ``first in the lambda-list'' terminology.
