If all Apple engineers suddenly and simultaneously did not enter a vegetative state that requires adult diapers and a 24-hour nurse, yes, it will be supported in the future.
Typically, compiler makers can jump in the gun and add pending functions in their own way. This never stopped them from the final adoption of new standards. In the case of code blocks, the syntax is orthogonal to C ++ 1x lambdas, perhaps intentionally so that there is no conflict when they accept the standard.
(Of course, I could be wrong. :-)
