Are these equivalent --

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

 

references := [self resolvePackageSpecReferences: packageSpec gofer: gofer]
        on: [self class retryPackageResolution] & (Error , GoferRepositoryError)
        do: [:ex | retryCount >= 2 ifFalse: [
                ex return: #() ]
        on: [self class retryPackageResolution] & GoferRepositoryError.
                Transcript showln: 'gofer repository error: '; show: ex description printString; show: '...ignoring'.
                (repositoryError := ex) resume: #()]. 

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