I've come to the conclusion that plot2d (via COERCE-FLOAT-FUN)
is actually trying too hard to get a numerical result;
binding numer to true causes some expressions to fail to
simplify, therefore making it harder to get a number.
I have a modification of COERCE-FLOAT-FUN (which applies numer
a little differently) which seemed to help. I';ll revisit this topic over the
weekend and we';ll see if it's any improvement.
FWIW
