Subject: invisible Infinity

Hi gurus and nubys,

I wonder, if you divide a Float by zero, you get Infinity:
 >> a=10.0/0
=> Infinity


and you can even write code using Infinity like:
 >> 0.upto(a) do |x| p x end
0
1
2
3
...

but if you try to access it directly you can't:
 >> Infinity
NameError: uninitialized constant Infinity
         from (irb):4

Should we be able to access Infinity directly? It seem a strange 
unexplicable behaviour to me, that it exists but is not normally accessible.
