[purs ide] extract namespace adt - #2878

👍 LGTM

Would it make sense to unify this with the equivalent type in Language.PureScript.Docs?

@hdgarrood but where would the type live? I guess in one of the AST modules?

I think Names might be more appropriate? Is the Ide code not able to depend on Docs at the moment though?

I think I'll leave this PR as is for now. I think it totally makes sense to have this Enum somewhere in the compiler, but it's probably not only Docs and Ide that would use it.

Segmentation fault/access violation in generated code

Doesn't sound good, but seems to be related to getting the git revision on the AppVeyor instance? Definitely isn't caused by this PR.

Oh dear :/ Might be worth trying to repro with a local Windows VM, and perhaps seeing what happens with GHC HEAD too? I found this patch which was recently merged https://ghc.haskell.org/trac/ghc/ticket/13108#no1 which slightly improves this error message we're seeing.

The tests works just fine on my local Windows machine. Must be something AppVeyor specific.

I suppose there's a possibility it's due to us running stack slightly differently locally and on AppVeyor? Eg, does it make a difference if you run with --jobs=1 like CI does?

Still doesn't break anything on my machine. I'll just merge this PR since it doesn't cause the failures and I'll open a separate issue for the CI failures?

Sounds good to me.
