That said, I'd expect the compiler to call sin(y) only once, so it'd be
more like that:
auto sinY = sin(y);
for(int i = 0; i < x.length; i++) {
x[i] = sinY[i];
}
And I'd expect that because in the expression "x[] = sin(y)[]" none of
sin's argument are part of an array operation. Calling a function
repeatedly should only happen when one of its arguments can change
between iterations (and possibly only pure functions should be allowed
to be called repeatedly through array ops).
