/// | ||
/// Forbid imports which use an expression for the module argument. | ||
/// | ||
/// ### Why is this bad? | ||
/// | ||
/// Import statements which use an expression resolved at runtime makes it to find where the | ||
/// import comes from and some static code analysis tools might not be able to resolve them. | ||
/// | ||
/// ### Example | ||
/// ```javascript | ||
/// // Bad | ||
/// require(name); | ||
/// require(`../${name}`); | ||
/// | ||
/// // Good | ||
/// require('../name'); | ||
/// require(`../name`); | ||
