efficient way for building class browsers.

Only a browser?  Text or GUI?  What OS?  Any particular GUI toolkit?

compiler.ast can be used for this, but only produces proper results when 
the file has no syntax errors.  Don't get me wrong, using the output of 
compiler.ast can be a pain in the ass, and slow as hell (5 seconds for 
100k of source on a celeron 400), but it can be used.

You can write a limited parser (subject to certain flaws), one that 
doesn't use tokenize or compiler.ast, and get pretty fast results.  I 
wrote one to go into my own editor PyPE (pype.sourceforge.net), and it 
has no problems parsing a 100k Python source file and displaying the 
source tree in a GUI in less than 1/2 second on a celeron 400.

It wouldn't be too bad to pull the tree portion out, what kind of 
browser do you need?
