I once wrote a pure C project years back that made heavy use of complex numbers and 2D/3D vector math. At one point I got so fed up debugging my expressions under an endless parentheses-hell of `vadd(vmul(vadd(...), vadd(vmul(...))))` that I threw my hands up and changed the file extensions to .cpp just to use std::complex<T> and enough operator overloading to type vector expressions like a human being.
