Merge with singledispatch?

[catern]

Hi, love the project, I've definitely wanted better mypy support in singledispatch before, as well as other more advanced features.

That being said, it looks like mypy is going to add support for a singledispatch plugin. Maybe there's some opportunity for collaboration?

I would love to!

But, there are several features of classes that won't be supported:

• Like Supports[] type
• or hypothesis plugin that I am working on right now

So, I am open for any collaboration, but I am almost sure that these two projects won't be merged.
