balls, you say? I remember being hunched over an IBM 5100 (the first
PC?)
for months on end coding AR filters on semiconductors. The screen was 
about 3 inches by 4 inches, about 4 inches off the desk. But it really
worked, was built like a tank, and was only about $15,000, as I
recall...
and APL worked like a charm for that application.  

Just don't let anyone mess with your globals =)

But you know, an explict FUZZ brings the float comparison problem
out in the open and promotes documentation. Now, if you are going
to use floats as keys in a dict, heaven help you!
