Python source spider/AST analyzer

[GoogleCodeExporter]

It is not clear how to measure popularity of some Python constructs. It can be 
useful to provide proof for the statements like this 
http://bugs.python.org/msg131743 

What is the expected output? What do you see instead?
Source spider can crawl *.py sources on the web (or local library or projects) 
and to build abstract syntax tree (AST) of these sources and provide search 
capabilities to find, for example, all calls of
  print "something", 
statement.
