-Branching
-
-Branching in Collapse OS is limited to 8-bit. This represents
-64 word references forward or backward. While this might seem
-a bit tight at first, having this limit saves us a non-
-negligible amount of resource usage.
-
-The reasoning behind this intentional limit is that huge
-branches are generally a indicator that a logic ought to be
-simplified. So here's one more constraint for you to help you
-towards simplicity.
