    In system 44.2, with microcode 692, on Lisp Machine Thirteen:

    I gave MACSYMA:SIMPLIFY a compiler:optimizers property of (MACSYMA:OPTIMIZE-SIMPLFY).
    The action of COMPILER:OPTIMIZE is not correct, it FIRST calls the
    optimizers property, and THEN checks to make sure the number of arguments
    it passed was correct given the %ARGS-INFO in effect at the time.
    Also, in this case the function SIMPLIFY had not been defined, so
    the call to %ARGS-INFO caused an error. 
I guess I'll have to remodularize some code in the compiler to fix this
right.  I'll put it on my list.
