Steve Handerson has pointed out that MACRO-FUNCTION also needs an
optional evironment argument, since without this we have no way of
getting hold of the expansion function for a lexically defined macro
(though we can execute this function). This may or may not be important
for normal code, but it is definitely important for writing environment
tools such as a single-stepper.
Yes. I don't remember why, but apparently it was important to something in
NIL. I don't think it was just the stepper. From the looks of the
sources we put this in last october or earlier.
