Then you should probably use a language that lets you write DSLs for any given domain, rather than abusing operator overloading which just happens to work for a few subdomains of mathematics (e.g., you can't use mathematical conventions for dot product multiplication in C++). Anyway, I've never seen any bugs because someone misunderstood what a `mul()` function does, but I've definitely seen bugs because they didn't know that an operator was overloaded (spooky action at a distance vibes).
