Does this work:

def foobar(translate):
     _ = __builtins__._

xgettext has an option "-k" which allows you to specify an 
additional "keyword" (like a function name, I guess) for detecting 
translatable strings. With the orig_and_trans() function, the 
following command produces a messages.po with "hello" in it.

xgettext -korig_and_trans source.py
