These are the Ada expressions for the mathematical "all" and
"existence" quantifiers and read quite naturally.
Draft 10 of RM 2010 defines some as a new reserved word.

This is silly English, and when I try to make sense of it, I arrive at
the all quantifier. So I think, just for avoiding a new reserved word,
this is a very bad proposal.
