We actually have the ~= operator that's basically that-- not sure if it's allowed in requires-python. But that's not sufficient. You also need an "or" primitive if you want to express "~= 2.7 or ~= 3.4". Right now all you could write is "~= 2.7 and ~= 3.4", which is the null set :-). -n -- Nathaniel J.
