Ah, this should be guarded with && isempty(methods(range, Tuple{Any,Any})), while the tests should not. However, on 0.7, that does not work, because of the deprecated, old range(a, len) methods. That also makes me wonder whether we actually should be adding this method on 0.7. I'd say yes, but might be worth discussing.

Heh, thanks to #511, this definition actually works on 0.6, too. But there we have the keyword-argument-less, two-argument methods, too. However, if we omit the Base qualification, then this will add a method to the existing Compat.range on 0.6 and to Base.range on 0.7 and later. Doesn't sound too bad.

Still has the bogus && isempty(methods(range, Tuple{Any,Any})).

What replacement do you recommend given that the PR hasn't been merged (can't use a precise v"1.0-xxxx")?

None. We want the tests to be run on all versions (0.7 and up, actually). If you look at the other tests, they don't come with an upper version bound. If Julia is recent enough that Compat doesn't have to do anything, we still test things work as expected/promised.

So that would be

if v"0.7" ≤ VERSION

then?

Yes. (That's what I tried to say in #633 (comment)).

The condition should be completely removed now (assuming we succeed in making this work for 0.6).

@test range(0, 5, length = 6) == 0.0:1.0:5.0
@test range(0, 10, step = 2) == 0:2:10
end
