Please kill the comma operator with fire. Is is just bad.

Or, if you really want to distinguish them, this would work:

I am a regular Python user, and I advise against using this
syntax for tuples. I have been bitten many times by something
which I thought was a tuple becoming an expression and
something I thought was a simple expression becoming a tuple.
It may be less of an issue in a static language, but it will
still be an issue. I don't have an alternative syntax to
propose.
I'm not familiar with Python. What is the difference between a
one-element tuple and an expression? Are Python tuples just
arrays?
