* being a class that implements Singer). The virtual call
* singer.sing() is effectively replaced with the static call
* Bird.staticsing(singer). Bird.staticsing() may perform
* operations on its parameter which are only allowed on Birds,
* rather than Singers. The Insert Redundant Casts option inserts
* a cast of singer to the Bird type, to prevent complaints from
