I agree, but see this as similar to the naming convention:
            long_symbolic_representation     at first glance,
                                             this looks like
                                             three names
why not:
            longSymbolicRepresentation?      this makes the oneness
                                             clearer

Returning to the subject line - When will the final decision be handed
down?

My own preferences are: (1) transform or transformer not decorator
                         (2) the transforms should follow the thing 
being
                             transformed. i.e. after the script has
                             declared the name.
                         (3) a list of transforms.
                         (4) the list should have one entry per line,
                             to make reading easier.
