I [recently ran into some unexpected behavior](https://github.com/JuliaLang/julia/issues/23450) with the `@parrallel` operator that I think might warrant a syntax change. In particular, since `@parallel` requires specification of a reduction function for value returned by each parallel run, I assumed I should be working with the `@parallel` call similar to how I would treat a function, and included a `return` statement. But turns out, `julia` sees `@parallel` as a loop, and so the return statement caused it to exit the `@parallel`, causing some very hard to figure out errors.

Might I suggest allowing `@parallel` accept `return` statements? It’s implicitly using return values from every pass of the loop, seems like it should allow them to be declared explicitly.
