I assumed that in my response but also GvR and the Python community
can do too much with @.

:-)) OK, of course I was talking about the semantics within the
language framework. Otherwise you could claim that def says deaf and
for says four ;-)

Sometimes it's an advantage to be a non-native speaker. I know exactly
one meaning of yield (something like deliver) and that fits nicely to
generators. :)
