Yup.  Actually, I've never seen it with &f, only with calls into the dynamic
loader to get the address of external routines in a shared library.  In fact,
if you make back to back calls to get the address of a routine, you get two
different values.

I haven't tried hard to see if I could get &f to give back two different 
answers, but I bet it would if I spent some time working on it.

OK.  This sounds safe for HPs :-)
