Yes. The RHS of a let binding is a dynamic expression, and involves no static
checking. The RHS of an import is a static module expression with validation --
it checks that the thing you're importing exists, and also prevents you from
importing the same name multiple times.
For example:
module M { export var foo = 42 }
let { bar } = M; // dynamic error, not statically caught
vs
module M { export var foo = 42 }
import M.bar; // static error
And also:
module M { export var foo = 42 }
module N { export var foo = "foo" }
let { foo } = M;
let { foo } = N; // either shadows or reassigns, no error
vs
module M { export var foo = 42 }
module N { export var foo = "foo" }
import M.foo;
import N.foo; // static error
