That's not the full syntax. The full syntax is
[ <test> for <exprlist> in <testlist> <list-iter-opt> ]
where
<test> can be an arbitrary expression: and, or, lambda, +, -, ... <exprlist> can be a list of expression, except for boolean and relational expressions (but I think this is further constrained semantically) <testlist> list a list of tests <list-iter-opt> is optional, and can be another for or if block
Aren't these names a bit mixed up w.r.t. what's in that position? As far as I know
<test> is not a test but a function as it produces any value not just True/False
<exprlst> is a list of names, not arbitrary expressions
<testlist> is anything which will produce an iterator
Or so I've understood so far.
So a more complex example is
[ lambda a: a[x]+y*z for x,y in A for z in B if x > z]
I'm schocked ;-)
