Indeed.  I don't remember if I already wrote this, but I looked up my
notes and it comes from Dolphin.

The Squeak image I have has both #sendTo: and #sentTo:, but the
implementation of #sendTo: is incomplet (it does not take into account
the lookupClass).  GNU Smalltalk has #sendTo: *and* #perform: taking a
Message (I'm not extremely attached to the latter, but I agree that a
method to use in #doesNotUnderstand: should be there).
