#2739 Lists of Lists

SlimerDude Tue 19 Feb

If I have this class in podA then everything is fine, and podA compiles and runs:

class Lists1 {
    Obj[]?[] objs

    new make() {
        objs = Obj[]?[,] { it.size = 3 }
    }
}

But if I then make a podB and reference the above class:

using podA::Lists1

class Lists2 {
    Void main() {
        Lists1().toStr
    }
}

Then I get a compilation error:

Ticket promoted to #2739 and assigned to brian

I think that is because of differences in compiler vs runtime type signature parser
