[clean-list] more than one Start rule

[Claudio Potenza]

thank you for the answer on the field selection: I did search the 
document for something like it but couldn't find (but it is there).


Now another question:

I seem to have problems if I put "Start" rules in my implementation
modules (in addition to the one in the "main" project module).

This should be allowed (the langauge report mention it explicitly)
and is very useful for testing purposes.

But it seems that the compiler uses the first one that it finds,
instead of the one in the main module.

Am I the only one having this problem?
