The custom builder looks like a nice feature. However, since Python doesn’t support overloading, this might not be very intuitive. I’m thinking we could generate two classes: first a `class MyOp(OpView)`, and then a `class CustomMyOp(MyOp)` to attach any custom methods, such as `__init__` or others.
