The discussion so far made it clear to me that

a) there is a use case for this feature, although I never needed it myself
b) throwing new syntax at it is not the right solution

Especially since there seem to be slightly diverging ideas about the exact
details in behaviour. Since this can be done in form of a library, people
should just drop it into a couple of competing libraries and let users
choose what they like better in their specific situation. And since we
already have a PEP now, let's continue to use it as a basis for discussion
about how these libraries should best behave in general and what mistakes
they should avoid.
