“TypeError: in Tuple, in parameter, expected Type, got HTMLText” when iterating on 0.7.0-beta2.0

[ninjin]

The following simple example runs fine using Julia 0.6.4.

using AbstractTrees
using Gumbo

for el in PreOrderDFS(parsehtml("""
        <h1>
            Foo
        </h1>
        """))
    @show el
end

However, on Julia 0.7.0-beta2.0 it goes down in flames.

I am sure this is due to some changes that came with 0.7, but I am still working on catching up with the release so I am not entirely sure what is going wrong.

Hi @ninjin, Gumbo doesn't support 0.7 yet, so this is not at all surprising, probably almost nothing will work. You can track progress on 0.7 support in #52!

Thanks @porterjamesj, apologies for missing the PR, only checked the issues and saw nothing about 0.7.
