I suppose it is, as it's technically correct, but it's also a HUGE source
of confusion, particularly for newbies. IF this is being touched anyway, is
it possible for the interpreter to know when this error is generated that
this is a bound method expecting a "self", rather than an arbitrary
function with n parameters? In which case, it would be really nice if the
error message replaced that somehow, maybe something like:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: append() takes 1 positional argument in addition to the
automatically added instance object -- but 2 were given in addition to the
Man -- hard to come up with good wording for that -- but SOMETHING that
lets users know what they actually did wrong would be good :-)
If it's not do-able, then still +1 on making builtins consistent.
