Do you mean making sure method exists given the code $x->method()?

How do you expect the linter to know all of the classes of which $x could be an instance and all of the namespaces whose name $x could contain.

I guess you could do an imperfect job if you knew some possible values for $x. That raises the following question:

How do you expect the linter to know any of the classes of which $x could be an instance or any of the namespaces whose name $x could contain.

Update: Now takes class methods into consideration.
