    In system 25.0, with microcode 612, on LISP Machine Two:
    When you get an undefined-function error in the evaluator, it is
    EXTREMELY ANNOYING that when you type Control-R to the error
    handler you are asked for a value to return from SI:*EVAL,
    rather than a new function.  In general when some quantity
    is in error, Control-R should take a new quantity to replace
    the defective opne, and not decide to return from some arbitrary place.

c-C is the command for performing that operation.  c-R means specifically,
"return a value from the selected frame".  c-C also likes to "fix the error"
by defining the function; we should probably have another command
which fixes this specific error but doesn't define the function, setq
the variable, etc.
