DylibBinder Generic Parameters Being Redeclared in InnerElements

[tj-devel709]

There is currently an issue where there can be a typedeclaration that has an innerStruct (for example). This inner struct can reference the typedeclaration's generic parameter T0. We would expect that the typedeclaration declares this generic parameter but right now, both the typedeclaration and the innerStruct declare it.
