Oops.  I didn't answer this.  To support logarithmic plotting (of the
x axis), we replace the original function f with a new function fun.
When doing log plotting of the x axis, we sample the x axis
logarithmically by converting the x samples to log(x) samples.  To
compute the corresponding y value, we need to compute f(exp(x)).  This
is what the flet fun is for.

How this can cause a stack overflow with clisp and sbcl confuses me.
