indeed, the recursivity of the issue utterly destroys the "safety" 
argument.

however, i still like annotating the "emissions" themselves, simply to 
make it obvious that this is only a "notification" and as such not 
expected to directly affect the current scope (yes, i know that signals 
are sometimes abused for implementing callbacks - shame on them). kinda 
the opposite of the safety argument, really.

that can be enforced with tooling, though.
