No application developer will quickly figure out what a tilde means. Maybe it means 'roughly', but it requires too much thought and is ambiguous. 2.5 is not roughly 2.5.2. It is the same exactly.

Tarek,

I am a bit confused at the current proposal combined with the newly introduced range operator.

Would "Requires-Python: <=2.5" include 2.5.4 or not?

Also, "Requires-Python: 3" would include all 3.X versions, correct?
