Given a class/interface/struct, I'd like to duplicate it's design exactly, as if I copied and pasted directly from the source and just changed the name. I need to inspect the contents too. Is this possible with D?

Main things I'm thinking will fail are (multiple) alias this unless there is a way to get which variables are aliased to this.

The idea is to be able to make sure one can modify a class and drop it in for the original and it work in all cases. With alias this, it can fail unless we can alias it too.

struct X { int y; alias this y; }

struct XX { mixin DupStruct!X; }

If DupStruct cannot handle the alias this then XX can fail to mimic X completely.

This sounds like mocking, this answer might be of help: https://forum.dlang.org/post/gdfvbrknbnbfunycbvwd@forum.dlang.org

I don’t know the capabilities of these libraries, but you may want to have a look.
