I've been thinking of an Immutable Builder pattern and an operator to go with it. Since the builder would be immutable, this wouldn't work:

long_name = mkbuilder() long_name.seta(a) long_name.setb(b) y = long_name.build()

I think the more pythonic way is: y = build(a=a, b=b) A Builder pattern is less used in Python due to the support of keyword arguments.
