Everything Should Be Typed: Scalar Types Are Not Enough
Relying only on scalar types creates subtle semantic bugs that bypass compilers because they cannot distinguish between different domain concepts, a risk not fully mitigated even by grouping parameters into structs. The solution is to wrap every meaningful domain concept in a distinct "newtype," ensuring the compiler enforces semantic correctness and leading to safer, self-documenting code with compile-time validation.
