Consider the following:

package foo
class Bar {
  static def prop
  static def getProp() {}
}
class Baz extends Bar {
}

import foo.Baz
Baz.prop
Baz.getProp()

Baz b = new Baz()
b.prop
b.getProp()

b.prop is showing as field reference but should be property-style reference to getProp (as Baz.prop is showing), since the reference is made outside of Bar or Baz class bodies.
