I suppose if it's an expression, it must be valid, eh? Otherwise it's something else.

The first part of the list comp can be any valid expression.
Does that mean that there are invalid expressions? I'd enjoy seeing an example.
Here's an obvious one:
j = [foobar(item)/0 for item in x]
I like Kent's response.
foobar(item)/0 is a "valid" expression. It fits the grammar of expressions. The fact that it raises an exception does not make it an invalid expression.
Consider foobar(item)/xyz. It is valid. If xyz == 0 then it will also raise an exception.
