[clpython-devel] Problem with Python 'open'

Hi --

I have CLPython running on a small example with no I/O, but when I try opening a file I get:

Error: Incorrect keyword arguments in (NIL "r") . While executing: OPEN, in process listener(1). Type :POP to abort, :R for a list of available restarts. Type :? for other options.

for

open(f,'r')

or similar error:

Error: Incorrect keyword arguments in (NIL NIL) . While executing: OPEN, in process listener(1). Type :POP to abort, :R for a list of available restarts. Type :? for other options.

for

open(f)

Suggestions please! I'm not much of a Lisp hacker, just trying to get a Python script to run (much) faster.

Thanks.
