Got a 10x speedup in aurora-rust today by accident.

3ms → 323µs

I pick the second—clearer intent, fewer footguns, better APIs.

Some junior devs forgot there’s a thing called Find & Replace. They only know AI now 🤡

@davepl1968 I found it in my first-year notebook 😁

[Abinash Karmakar @codeAbinash]

@davepl1968 I wrote an expression evaluator in C++ a few years ago when I was learning programming. Back then I didn’t know another way to build it 😢.
