So basically you're saying that if I want to add mathematical expressions to my JIT'ed code I should obfuscate the purpose by writing multi-line operations to build them instead of having the ability to plonk it in more or less verbatim?

As I said, I fully agree that operator overloading is horribly overused but the purpose of this JIT is to quickly create JIT code with customized expressions then those expressions should be possible to write fairly verbatim instead of following something with a religious zeal (is even matrix multiplication allowed to overload?).

And yes, AST's usually contain a lot more information such as source-location,etc for debugging (here it'd be interesting if an operator overload is able to take C++20 source_location as default parameters), but again this is for a specialized jit.

As for passing more options to mul nodes, a mul node is just that and nothing more (only extra interesting data in a restricted scenario as this would possibly be source_location as noted above).
