Hmm.
assert_statement: "assert" expression ["," expression]

That's pretty obvious to me: it only takes a single comma. And note that the
last expressions is an 'expression', *not* an expression_list. This means
that it has to be a single expression, and if you want it to be a list of
expressions, you need to make it a single expression by adding parentheses.

(You can look up the definitions of 'expression' and 'expression_list' in the
sections 5.10 and 5.11)
