I ran into another unused value bug.

Code:

main() {
	ab := "a" + "b"
	assert ab == "ab"
}

Error:

    ab := "a" + "b"
          ┬
          ╰─ Unused value '"a"'

Yea this should be a different type of error. String concatenation currently has no implementation.
I'll make it fail as "Not implemented" instead and later we'll implement the real thing.

cli/q@4cb94d758f now shows a proper error message.

Tests that must return the new error to pass:

Let's consider this finished for now and re-open string concatenation as a new feature proposal in the future.
