is a gc all that relevant if you're not dynamically allocating in either case?

  Garbage collection by its nature implies dynamic allocation. You're using value types and raw pointers in those targets because even the memory overhead of a heap/freelist/etc can be too much. With things like AVR you're looking at 512B to 16kB of total memory(part of which includes the code you write).

    > Garbage collection by its nature implies dynamic allocation i'm not sure i follow - you're saying that a gc existing implies that one cannot preallocate and avoid dynamic allocation?

      > preallocate This will still use dynamic allocation to do the preallocation. You'll have a heap to track this which comes with its own overhead.

        i guess i was using 'dynamic allocation' to mean allocation that occurs in the midst of the main control flow, likely in response to some conditional evaluation (vs upfront).

          Yeah, if you allocate in the main loop or preallocate you're still going to pay the overhead of a heap to keep track of those allocation :).
