A new C++ back end for ocamlc (github.com)

The ocaml/ocaml pull request proposes a new C++ backend for ocamlc, replacing the older non-incremental C++ generation used by the runtime/FFI. It demonstrates compiling a purely functional OCaml prime-sieve program into readable C++ templates via ocamlc -incr-c, and discusses how C++ template depth and interpreter choice affect build/run behavior. The author notes that larger computations can require special flags and improved algorithms, and suggests the approach could potentially be extended to other languages in future work.
