This was ambiguous because it was unclear, as MvL stated, if "2.5" was just "2.5.0" or included versions like "2.5.1" or "2.5.2". How about having "2.5" match all 2.5.x versions, and "2.5.0" match only 2.5 itself? (ditto for "2.5.N" matching only 2.5.N for N >= 1)

This "~=" operator looks murkier than it needs to be IMO. An implicit range operator is simpler indeed, and achieves the same goal. Meaning that "<=2.5" for example, will be translated to "<=2.5.x" as well.

So that "2.5.4<=2.5", "2.5<=2.5.2", but not "2.5.4<=2.5.2" (i.e. A<=B, B<=C, but not A<=C)?

I find that strange.
