    Strings and Arrays are immutable as to their size.  Thus, the #remove: 
    message and its progeny, unsurprisingly, don't mean much in these 
    contexts.

That was his point.  The operation does not in general make sense,
and yet *this* call is quietly allowed.  The surprising thing is not
that #removeAllSuchThat:  *doesn't* "work" for Strings, but that sometimes
it *does*.

That's why removeAll-raok implements this method as "self shouldNotImplement"
so that _all_ calls to the method with an Array or String argument will
report an error.
