The problem with this one is that you need a way to express all the other stuff in import statements like "qualified" or "as", the imported list, etc.
If you don't like the dots and are willing to deal with having to type the current module hierarchy twice, a more verbose syntax would be
Proposal Translation -------- ----------- module Foo.Bar.Baz.Bing where module Foo.Bar.Baz.Bing where from Foo.Bar.Baz import Blip import Foo.Bar.Baz.Blip as Blip from Text.HaXML.XML import Types import Text.HaXML.XML.Types as Types import Escape import Text.HaXML.XML.Escape as Escape
Not as tight as the prior syntax I proposed, but more readable and still a large improvement on the status quo.
Thoughts?

Problem details:
* Hierarchical module names are getting really long (including a functional area, a package name, and a module name).
* People typically import multiple modules from areas close to each other in the hierarchical module namespace (especially in the case of intra-package imports).
* Long module names are required even for non-exposed modules because a program may contain only one module with a given name (regardless of its visibility).
Idea: Allow module relative imports in a manner that does not break any existing code.
This would be really nice, but I'm not sure I like the way you propose to do it. Those bare dots don't look very nice to me, and I really don't like the idea of having to count them... I'm not even sure I like the idea of imports relative to the current module.
I almost want "import Text.HaXML.XML.{Types,Escape,Pretty}", but not quite. And that would not be nice for qualified imports, anyway.
Maybe something like
from Text.HaXML.XML import (Types, Escape, Pretty)
would be nice.
