The way I see it, THOSE are inconsistent. Think about it in an
object-oriented way. It doesn't make sense to ask an object to "delete"
itself, because the object isn't in control of where it is stored. You
have to ask the OWNER of the object to do the delete. It's the OWNER that
has to take an action. Thus, something like "l.del()" would be a bit
This is the same as C++; objects are deleted using the "delete" operator,
not by asking an object to delete itself.

Well, the len() function does call a a method. Now, it's just syntactic
sugar. However, until Python 2.0, types like strings could not have
methods, so you needed a global function.
