keyword arguments for `static_hasmethod`?

[cscherrer]

I think Tricks ought to be able to help us with KeywordCalls, especially cscherrer/KeywordCalls.jl#16.

But static_hasmethod seems to be missing keyword argument support:

julia> methods(static_hasmethod)
# 1 method for generic function "static_hasmethod":
[1] static_hasmethod(f, t::Type{T}) where T<:Tuple in Tricks at /home/chad/.julia/packages/Tricks/TyBuj/src/Tricks.jl:17

julia> methods(hasmethod)
# 2 methods for generic function "hasmethod":
[1] hasmethod(f, t; world) in Base at reflection.jl:1347
[2] hasmethod(f, t, kwnames::Tuple{Vararg{Symbol, N} where N}; world) in Base at reflection.jl:1353

For example, this works:

hasmethod(g, Tuple{}, (:a, :b, :c, :d))

You probably couldn't call it this way to resolve it statically, but maybe this could be done by representing the symbols at the type level, as in named tuple? Or maybe there's a fundamental problem with trying to reason about keyword arguments statically?

Yeah, I am sure we can make this work.

We were able to update KeywordCalls without this, using hasmethod in the body of the macro (outside the quote). Stating the obvious, there's still lots of value in adding this functionality.

Also, cool package. Thanks for your work on it :)

Yeah that is not a good as this, since it will not react to things being added interactively.
I am not sure it will react correctly to methods defines in packages loaded after this one or not either.

Good point, thanks. In this case it's just there to avoid warnings for defining duplicate methods, but we should check that. I'll add an issue.
