Parentheses are usually more robust for multi-line, where possible:

    foo = (bar
        if some_condition()
        else baz)

The lines can more easily be edited and rearranged without fiddling
with backslashes at the end of every line. (For even more robustness
at the cost of space, separate the parentheses so they're on separate
lines from what they enclose.)

It also addresses the original poster's complaint that there's no
early signal of the compound nature of the expression: the opening
parenthesis signals this.
