This PR extends "Duplicate identifier: X" errors by also printing the range of the already existing identifier. This isn't currently possible for scoped locals (
let,constin a block) that use a shared declaration (multiple names share the same local), but works for anyvar, class member, namespace member etc. Also fixes the assertions triggered previously.
