I’m not sure this count is helpful. It’s just for the assertion?

This evaluates the assertion twice in debug builds. It’s not obvious how to avoid that. We can probably live with this for a while, since it affects the macro not all the macro call sites.

Please do remove that FIXME.

There is no need for the get() here. You can pass a RefPtr to a PassRefPtr without it. Unless frameCreated takes a raw pointer. In which case I wonder why owns the subframe proxy below.

I probably would have done this in one line without the local variable. Also, if frameCreated takes ownership, this should be release() rather than get().
Since subframe is a word, I would not capitalize the “f” in this local variable or in function names.

Could just name this isGoodKey since the map will be right there was the template argument.
As we discussed, this would be great as a public HashMap static member function.

This implementation may be as good as we can achieve, but it gives the wrong answer for maps using non-default traits. We should consider making the trait typedefs public so they can be used for things like this.
