However, perhaps the correct answer is for senior monks to start using a standard convention when the language in question is not obvious from context:

    # P5
    print $foo{bar}.baz();   # bar entry of %foo, 
                             # then concat result of baz()

    # P6
    print $foo{bar}.baz();   # call baz() method on
                             # bar entry of %$foo
