Re: Syntax errors in autogenerated packages

I encountered the same kind of problems in version 4.0, in the following 
situation :
a long long compound expression, in a cell marked as "initialization cell", 
intended to generate a ".m" file.

The solution I adopted finally is to enclose the compound expression with (), 
i.e. :

myFunction[args___]:=Module[{vars},
(
expr1;expr2);
...
(exp3;expr4)
]

I might be wrong, but I suspect the parser to be disturbed when compound 
expressions are longer than a certain integer.
