Force specialization on varargs when the arguments are not all of the same concrete type

[dilumaluthge]

On a separate note, I have an analogous question about forcing specialization on keyword arguments:

Force specialization on kwargs

If I have a function like this: f_vararg(varargs::Int...) = tuple(varargs...) I can force specialization on varargs with either of the following: g_vararg(varargs::Vararg{Int, N}) where {N} = tuple(varargs...) h_vararg(varargs::Vararg{<:Any, N}) where {N} = tuple(varargs...) Now suppose instead that I have a function like this: f_kwarg(; kwargs...) = (; kwargs...) How can I force specialization on the keyword arguments?
