I'll give you a short answer now, and perhaps I'll have time to 
investigate more fully later.

Compound statements, like

import this, that

needs to get expanded into multiple tags.

In wisent-java-tags.el, see the line:

    semantic-tag-expand-function 'semantic-java-expand-tag

and the function semantic-java-expand-tag.  If the import is modified to 
have all the names in it, a python version the expand-tag function could 
expand it into multiple tags.

The name list will need to explicitly start consing the names together. 
  See qualified_name_list in wisent-java-tags.wy for an example.


Good Luck
Eric

Hi,

   I checked in a change to the python parser to better support imports 
with multiple names.  I did this by making the dotted_as_name_list 
return a list of names, not just single names.  I then added an expand 
function in wisent-python.el to convert the compound tag into different 
individual tags that happen to exist in the same space.

   It could be made better by remembering where the names are, and 
shortening the tag overlays to match the name locations, but for now, 
this made things much better.

Enjoy
Eric
