Mel.
Thanks for your answer. I wonder if this is a bug, or did I miss
something in the docs ???

Hi,
the following code does not work until I ommit the a=0 statement.

Can anybody explain what is going wrong here ?

Dear python users!
I try to setted up compile-free parallelism using the exec command.
However I had some problems with namespaces which I find mysterious
although I managed to work around. But the workaround is not nice, so
I wonder if there are ways.

So when you exec 'a = B' in globals(), locals() you might think you
were changing the local namespace. In fact you are changing a copy of
