Splitting kwargs into specific keyword arguments?

General Usage

As far as I am aware, this is not currently possible. You cannot dispatch on keyword arguments in general.

One workaround, off the top of my head, if you don’t mind using positional arguments for funA and funB:

funA(a=2.0) = a
funA(::Nothing) = funA()
funB(b=4.0) = b
funB(::Nothing) = funB()
useAB(; a=nothing, b=nothing) = funA(a) + funB(b)
