Re: fixing infinities and ranges etc

I'm not sure I entirely understand the proposal- does it change Inf aka ∞ ?

Otherwise I like it, and prefer the X::NegInf and X::PosInf,spellings as
being easy-to-understand & a good Huffman-encoding.

Before/AfterEverything are also easy to understand, and would be as natural
to use for sorting strings, eg. for saying if a database NULL should go
before the empty string or after everything else. On the other hand, if
I'doing something with tangents and handling pi/2, I'd rather be thinking
about PosInf as my exception and not AfterEverything.

X::BE and X::AE are too short to use outside of this discussion, especially
as "BE" is the common verb "be."
