In fact, I think the below examples are reasonable uses that do a better job of expressing intent than the if statement would. I just don't like the mental backtrack they require, and would like some sort of advance warning. Parentheses at least tell me "You're not done yet; keep reading."
ack(r,r) if r not in cache
log(message) if error_flag
I think you've misunderstood the nature of the change. HTe new conditionals are *expressions*, they aren't postfix conditionals for statements.
Right, but the only effect of that on the examples is that they both need an 'else None' continuation or thereabouts.
I also predict widespread over-use of the new toy and agree with Jim that mandatory parentheses around the whole (X if Y else Z) construct would ameliorate legibility a bit.
