What's the concrete advantage of if blocks over conditional jumps? The primary answer in all three cases is surely "expressiveness". If I came upon code like that, it would take me a while to understand its intent - does $value end up as an array, or something else? what's the ?? there for, and when will expression C be used? Now, it may be that the task in question isn't common enough to deserve its own syntax, or you may not like the proposed syntax, but I think that's very different from coming up with lots of clever ways of writing something, and requiring new syntax to have a "concrete advantage" over each one.
