Why do you want the 'where' there?  Why not simply treat a file
Foo.Bar as a concatenation of module Foo.Bar and optionally modules
Foo.Bar.*?
Because the module definition syntax is "module Foo[(exports]
where"... technically, it's not necessary, but it's nice.
Additionally, I don't think concatenation works well here, n-ary trees
work better. 

module Foo where
	import module Bar where
		import module Baz where
			quux = undefined
		quux' = quux . quux
	quux'' = quux' . quux'
quux''' = quux'' . quux''

would be nice.
