problem with lambda & list comprehension

[astrand]

Moved from http://bugzilla.lysator.liu.se/show_bug.cgi?id=1603:

Dear Sirs:

the following Python code line

f = lambda x: [v for v in x]

does not get through the pyobfuscate and generates an error when compiled (see below traceback report). Best regards,

Marco Lombardi
