Smalltalk, for example, where methods and instance variables
are utterly different things, and methods are always looked
up in the instance's class (doing anything else wouldn't even
make sense).

It's the way that old-style Python classes blurred this
distinction that has been responsible for much of the
complexity and confusion during the old-to-new-syle
transition that we're now in the midst of. Hopefully,
when old-style classes go away altogether, things will
become simpler and more consistent.
