Complete sequence API for list/tuple?

[birkenfeld]

I propose to add all methods present in PySequence (such as del_item) to PyList and PyTuple. It is quite convenient not to have to cast to PySequence for some operations but not for others.

Specifically on del_item - it should already be available thanks to deref to PyAny?

Though in general I'm in favour of making it easier for users, so happy to find improvements here.

We could also have .as_sequence() method on PyList and PyTuple to make the cast less awkward?

[birkenfeld]

Well, there's a few inconsistencies: for example, since the del_item is the generic version it will take negative indices :)

Ah, that's a good point! In which case a specialized del_item on PyList would be a good idea!
