The version I wrote (note that I did not like the distinction between 
'alias' and 'as', which is why the 'as' was mentioned as optional) with 
selective imports is what I would like to have - not that I'm that likely to 
use selective imports, but the idea of having the option is alluring. But 
I'm willing to settle for aliased imports (implicitly static, mind), for 
which the approximate grammar would be:

ImportDeclaration:
    'import' ModuleList ';'

ModuleList:
    ModuleDeclaration
    ModuleDeclaration ',' ModuleList

ModuleDeclaration:
    ModuleName 'alias' AliasedName
    ModuleName
