[Haskell] "&" does not get highlighted

[AllanZyne]

and

scope meta.function.type-declaration.haskell is wrong

[AllanZyne]

I think we may match operactors in this way: [^\w\s_\(\)\[\]"',:{}]+`

[wbond]

Is the & considered part of the same token as ==>?

For example 2, what scope should that token receive?

[AllanZyne]

Yes, I use code from this tutorial.

In example 2, I think that token could be "function parameter", but it can't be in "type-declaration".

BTW: I'm just a Haskell beginner...

@AllanZyne The Haskell syntax is currently being rewritten in #2225. Maybe test that and give feedback there?
