```I wonder if I can persuade the team to let me add a constant for the first
uncountable strongly inaccessible cardinal.

Regarding use-cases, I like the following one which is implicit in the
above observations about comparisons between infinity and integers.
Previously I would do the following a lot:

local tMin, tThisResult
repeat for each element tElement in tList
-- perform some computation on tElement to get tThisResult
if tMin is empty then
put tThisResult into tMin
else
put min(tMin, tThisResult) into tMin
end if
end repeat
Now you can do:

local tMin, tThisResult
put infinity into tMin
repeat for each element tElement in tList
-- perform some computation on tElement to get tThisResult
put min(tMin, tThisResult) into tMin
end repeat
