Christian, I'm copying you since I'm interested in your Senf. :-)
We are discussing whether
test() ==
for i in 1..5 repeat
j := i^2
output(i::OutputForm)$OutputPackage
output(j::OutputForm)$OutputPackage
should produce an error, saying that j is undefined.

Well, I have mixed feelings here. It seems practical to me to allow the current
behaviour as used in test() above. Moreover, what should
j: Integer := 0
for i in 1..5 repeat
j: Integer := i^2
output(j::OutputForm)$OutputPackage
output? It would be different from
j: Integer := 0
for i in 1..5 repeat
j := i^2
output(j::OutputForm)$OutputPackage
but I think the intention is unclear when these semantics are used.
