> luke: elsewhere in core the `__copy__` method had been used, so I was
just following precidence. I'm also fine with an explicit `.copy()` or
`.clone()` method.
Sure, I think it just happens that in this case it is simpler not to
implement `__copy__()`.
However, there is a way to implement `__copy__()` and still avoid the need
for calling constructors - like this:
{{{
#!python
class NoInitArgs(object): pass
class MyClass(object):
def __copy__(self):
duplicate = NoInitArgs()
duplicate.__class__ = self.__class__
duplicate.__dict__ = self.__dict__.copy()
return duplicate
}}}
