You didn't find all of the senders because caseOf: is inlined (see
MessageNode>>emitCase:on:value:).  Try doing "method source with it".  I
get 16 uses in the base image plus 9 more uses in my closure compiler.

Of course, still not many uses, but I still think it is useful for cases with a
small number of cases.  Its more elegant than a sequence of ifs and more
straight forward then creating a special static dictionary or other structure.
