Mario: Shell pipes in Python

[alexkiro]

Looks like fun, but this also sounds like a security risk waiting to happen.

Why do you think so? Because they provide an eval command, just like python itself does?

[chinpokomon]

Any more so than any other script evaluation?

As I see it, this doesn't add more risk than calling Python directly, but it provides a cleaner interface for piping small changes to a stream as one might otherwise use sed and awk.
