We're still not introducing any keywords either way, fortunately :-). 
'qualified', 'as' and 'hiding' are not keywords: the syntax after 
'import' has no place for lowercase identifiers, so we can use as many 
new words as we want, here, as long as module names stay capitalized and 
import lists remain parenthesized (or, import lists could equally well 
be in layout after 'where', 'of', 'let' or 'do' if we adopt the layout
