Macro hygienization doesn't consider type declarations to be assignments #8554
Description
E.g., in the following code I would expect that MyType gets replaced by a gensym, but instead it creates an actual type definition for MyType:
julia> macro def_my_type()
quote
type MyType
end
end
end
julia> @def_my_type
julia> MyType()
MyType()
If I add an inner constructor hygienization takes place, since the constructor definition is taken as a form of assignment to MyType.
