This is a typical mechanism that Tango used -- pass in a ref to a dynamic array referencing a stack buffer. If it needed to grow, just update the length, and it moves to the heap. In most cases, the stack buffer is enough. But the idea is to try and minimize the GC allocations, which are performance killers on the current platforms.
We keep solving the same problem over and over. std.internal.scopebuffer does this handily. It's what it was designed for - it works, it's fast, and it virtually eliminates the need for heap allocations. Best of all, it's an Output Range, meaning it fits in with the range design of Phobos.
