Does something like this exist? If no, are there alternatives where someone with no C/C++ knowledge can quickly explore and prototype language ideas? I’m particularly interested in use-def chains, coroutines, and to a certain extent - type safety.
I’m also interested in tracking produced values over multiple executions, and in later executions using the same value without computation if it has shown to produce the same value consistently. Is this something in the LLVM ecosphere currently, or is this more of a higher-level concept?
