All I can see is that it saves two characters per line—is that sufficient to warrant adding another way of doing the same thing? They're available in C/Obj-C because `+` for string literals *wasn't* available, but since Swift does support `+` for string literals, I think it's hard to rationalize adding this. > > -- > Adrian Zubarev > Sent with Airmail > > Am 16.
