	    Proposal #9: Variable Name Conflicts
	
	    Clarification:
	
	    Specify that it is an error for two parameters (including
	    supplied-p and &aux parameters) in the same lambda-list to
	    have the same (EQL) name.
	
	    [As previous discussion brought out, we could instead allow this
	    case with the last-bound (rightmost) argument shadowing previous
	    bindings in the same arglist, but this is certainly bad style and
	    interacts in nasty ways with the proposed change to the scope of
	    declarations.]
	Specify same for LET, LET*, DO, DO*, FLET, LABELS, PROGV, MACROLET,
	MV-BIND, and PROG.
    
    I don't know about DO*, but LET* should be able to shadow previous names.
    The restriction seems reasonable for the others mentioned.

Why should LET* be able to shadow previous names when LAMBDA expressions
cannot?
