import foo
def func():
    return foo.bar()

The snippet above will generate the following code;

  2           0 LOAD_GLOBAL              0 (foo)
              2 LOAD_METHOD              1 (bar)
              4 CALL_METHOD              0
              6 RETURN_VALUE

Though this will make things harder for specializing the LOAD_ATTR for modules since now the handling of LOAD_METHOD for that case is necessary so for the imports that we can infer during the symbol analysis pass, we'll generate LOAD_ATTR+CALL_ATTR instead of LOAD_METHOD+CALL_METHOD and hopefully the generated code will get specialized via the PEP 659.
