I have an instance of a parametric type. Is it possible to somehow retrieve the type parameters for this instance? E.g. for ```julia struct MyStruct{T} x::T function MyStruct(x) return new{typeof(x)}(x) end end ms = MyStruct(1.0) typeof(ms) I'd like to know the type parameter `Float64`.

[image] Gaussia: To try and figure out what it actually is, I wanted to look at the parametric types on by one. I see — this is for code exploration only. In that case, I would recommend dump, and of course reading the source code, but typeof(T).parameters is fine too.

Perhaps:

get_parameter_type(::MyStruct{T}) where T = T
