Yes, it is not allowed by the grammar. I think the reason is that 
the list items would become ambiguous (the difference between 
selected symbols and module names could only be revealed after 
semantic analysis). See for example:

import abc : cba, dcb, bca : acb, dbc;
// What is dbc? A module or a member of bca?
