Memory allocators can be simple. In fact it was an assignment for a course in the 2nd year of my CS degree to make an (almost) complete allocator.

However it is typically always more complex to make production quality software, especially in a performance sensitive domain.

Naive allocators are very easy: just subdivide RAM and defragment only when absolutely necessary (if virtual memory is unavailable). Performant allocators are hard.

I think we lost a great deal of potential when ORCA was too tied to Pony and not extracted to a framework, tool, and/or library useful outside of it such as integrated or working with LLVM.
