You can name modules that are imported, e.g.
Math :: #import "Math";
This way you can name-space functions, e.g.
y := Math.sqrt(2.0);
which can be helpful for naming functions, so in this example, you define
// in Math module
sqrt :: (x: float64) -> float64 {...}
// instead of
math_sqrt :: (x: float64) -> float64 {...}
