Hmmm, yes, I _was_ sort of assuming that __exit__ runs much
like 'finally' would -- otherwise cleanup/release code would more
often than not have to be duplicated.

I think THAT is the complicated part of the "do" syntax -- that trailing
"(whatever):" that I don't understand.  What would its pluses be?
Where would that 'whatever' be directed to...?  Could you please
provide a use case for with + "(some_argument):" ...?
