The system escape is interpreted, in multiline strings (IPython version 0.10):
In : '''
Isn't this incorrect?
Yes, that's incorrect. It should be fixed in 0.11, which we're aiming to release soon, but since it's a fairly unusual bug to hit, and relatively easy to work around, it's probably not going to get fixed in 0.10.
Thanks for the feedback!
You're welcome. I'm going to close this, because I can't replicate it on 0.11, and I can't imagine it getting fixed in 0.10. Let us know if it's a problem in 0.11.
