I get this error when in Python3 mode:

Traceback (most recent call last):
  File "/home/dblank/calico/Untitled.py", line 4, in <module>
  File "/home/dblank/calico/Untitled.py", line 2, in test
TypeError: unsupported operand type(s) for ^: 'int' and 'float'

which seems appropriate. And I get the number 886 when in Python2 mode. I'm running Linux (Ubuntu 14.04 64-bit).

[Doug Blank]

I'm running out of bitbucket master, FYI. Perhaps a difference in released versions?

[Keith O'Hara]

Also running master on ubuntu 14.04 and I only see the bug in python3 mode.

[Doug Blank]

Can you try setting menu -> Script -> Script Options -> Python2 mode and see if that makes a difference?

Oh, I see that you already said that Python2 works. Interesting...

[Doug Blank]

Looks like a mono version difference.

[Keith O'Hara]

Which version should I be using (What are you using?)?

[Keith O'Hara]

Still happens with

mono --version

[Doug Blank]

This works:

$ mono --version

[Doug Blank]

Can you try re-compiling with that version of Mono?

cd calico/Source
xbuild

[Keith O'Hara]

This makes it crash too! (Rebuilding doesn't fix it :()

def f():
    return 42 + "."
f()

[Keith O'Hara]

In fact

42 + "." 

in the shell also crashes.
