Okay, i just thought of another answer to this.
Scream at me if you find this hideous.
for x in [10, 20, 30] while y in [1, 2]:
print x+y
My previous message proposed colons to separate the clauses of
a list comprehension, which i now realize makes dict comprehensions
impossible (or at least a little strange-looking). If we use "while",
the lack of semicolons means that we can do parallel loops in
list-comps without colons, which in turn enables dict-comps.
