petdance/scratch — Issue #317: `NameSpace.add_sub($name, &sub)` does not honor given name for methods

The namespace.add_sub method accepts a name parameter for the sub object.
When passed a sub object that has the :method flag set, the given name parameter is ignored in favor of the name compiled into the sub object.

See in particular the code at [http://trac.parrot.org/parrot/browser/tags/RELEASE_2_6_0/src/pmc/namespace.pmc#L173 namespace.pmc, line 173] which I think is a bug.
