Timeline for Solidity: Is there any catch mechanism for throw? If not switch into return usage might be better?

You can think of possible responses as "yes", "no" and "unacceptable". Try to put your "guards up front" and don't change things in the first place if untangling it is a problem. You're describing some sort of partial success that you should probably break down logically - either total failure or complete success. | |

My if condition is a function and my change some states, which will return true or false. The function may consume a lot of gas. So it may seem to just use throw instead of if/else since reverting states by hand may consume additional gas usage. @Rob Hitchens

“unclear why funds are supposed to be sent to one of possible” Think it a system like an Amazon. When we purchase an item pay() first the money will be dropped from clients account. On the payMeBack(), condition check that for ex: does the item successfully delivered to the seller. If yes, gained money by the contract will be paid to the seller seller.send(gainedWei). If no, it will pay back to the client as refund client.send(gainedWei). Hope it is bit more clear. So mainly payMeBack also should decide who will gain the money seller or the client based on the conditions. @RobHitchens.
