Comment (by nbruin):
I found this suspicious (it's in the implementation of the
`_fast_callable_` method
{{{
+ self.__name__ = self.__repr__() # was clobbered by category mechanics
+ return etb.call(self, *map(etb.var, etb._vars))
}}}
One shouldn't touch the `__name__` attribute, and certainly not during
arbitrary executing code! Is it clear what code depends on the `__name__`
being identical to `__repr__`? Can we solve this issue (cheaply) during
`__init__`, or perhaps avoid the clobbering altogether?
