So it looks like it restricts the memory management to 100% scope based. I expect that makes a lot of designs for programs not translate to it as well as they fit in Rust or Java (for example). There are a bunch more constraining design choices they list further down:
> - Nothing ever moves
> - ... A string, an array of strings, a record with variable-size fields and an array of those records are each one contiguous block with no pointer in it
I'll have to look a bit deeper to decide if it's feasible to write many things in this language.
Might as well go back to ye olden days and put 100% of your memory in a giant preallocated block and instead of stack locals you just use the block. No allocation cost at runtime, cheese benchmarks by making the super arena.

I do that for the Playdate: statically allocate most of the large structures and tables in global variables, and don't call malloc or free after initialization is done.
I also put some things on the stack, not so much because I need to dynamically allocate or free something, often it's because I get lower access latency to the stack compared to main memory (because stack lives inside ARM's tightly coupled memory).
