Is there an easy way to display a struct definition?  
I often find myself wanting to see the fieldnames for a type, for which I can call `fieldnames(mytype)`. This doesn’t give me the corresponding types as well. Is there an easy way to say, call @printstruct(typeof(mytype)) and get:

```julia
struct MyType
    var1::Int
    var2::Vector{String}
end

```

or similar?
