Okay, here's another useless discussion, following up the recent one
about comparison of NaN's. Try this in Squeak:
1000 factorial < Float infinity "--> false"
This hydra just won't stay dead!
And if this example seems silly, just think of all the algorithms that
insert infinity's as initial values on paper, but for which C and Java
programmers have to use some sort of sentinel value like -1. There are
some serious cool points are at stake here, if we can make it possible
in our language to insert a plain old infinity.
