Your first Slang module

Create example/noise.slang:

module example.noise;

public float noise(float3 p)
{
    return frac(sin(dot(p, float3(12.9, 78.2, 37.7))) * 43758.5);
}

Import it from a shader on the project search path:

import example.noise;

Slang owns the module name, import, and language semantics. Workbench records the resolved dependency so an edit to example.noise invalidates its consumers. Continue with Modules and imports.
