It does not work on 7.3 and 7.4 when I try.

Looking at the currect cvs code it's not just parsing 'Infinity' as a
value, there is also an overflow check after float operations that will
exclude Infinity and Nan.

By the way, this thing was discussed on irc and I just sent a mail on
-hackers about it, not knowing about this thread here.

There are too many lists :-)
