() in bound var list

[JONL at MIT-MC (Jon L White)]

Perhaps one way to fake-out the interpreter is merely to have some
internal symbol to act as a shunt.  Thus the interpreter, when applying
"(LAMBDA (V1 () V2 () V3) . . .)"  would act as if
"(LAMBDA (V1 **INTERNAL** V2 **INTERNAL** V3) . . .)"  had been typed
instead.  There seems to be no problem with multiple occurences of the
same varialbe, and if it is truly internal, then the only loss is that 
it takes up space on the SPECPDL when used.
