equal to:

  [self model merge]
        on: MCMergeResolutionRequest
        do:
           [:request | request merger conflicts notEmpty
                ifTrue: [request resume: true]
                ifFalse: [request pass] ]

?

equal to

   [client unusedBytecode]
         on: MessageNotUnderstood
         do:
               [:ex | (ex receiver == client and: [ ex message selector ==
#unusedBytecode ])
                      ifTrue: [ self error: 'unusedBytecode' ]
                      ifFalse: [ ex pass ] ]

?

Not sure if I fully understood it, but is it just a reformat of the
syntax?  Or something more empowering?

(wait, is that, #on:do:on: ?  I'm confused on this one...)
