I would like a signature-preserving version. The help system, pydoc, the
inspect module, and likely any other introspection tool see those
decorated methods with a different signature than the original one.
Even if one writes a signature-preserving decorator (maybe along the lines
of this article by M. Simionato [1]), names like "self_foo", "self_bar"
are ugly. Furthermore, argument names are part of the public interfase,
but here they're tied to the implementation: what if later I want to keep
a reference to baz? I must change the argument name to self_baz, breaking
all users of the code.
