L1. Two vars, consts, enums, properties or events of one name in a program are an error naming both places (functions already were); the first used to win silently. A let / var of a name its own block already declared is an error (it used to shadow). A function with a result type whose body can reach its end without a return is an error, asked structurally of the body - a return, an if/else or a match with a default arm whose every branch ends - rather than handing back whatever the result slot held. The game, the lab and every package example pass all three; the lab had one harmless shadow, and the game's split screens had two real bugs of the kind. examples/rejected/ holds the four refusals, checked by the test runner's new reject_case.

A name is defined once, for every kind of declaration. Two functions with one name were
already an error; two vars or consts (or an enum and a const), or two property / event
records, kept the first definition silently. A game lost months to it: two files both said
KEY_LEFT, one meaning an arrow key's code and one a binding slot, and the menus read the slot.
They are now an error that names both files and lines. examples/rejected/ holds the two cases,
checked by a new reject_case in the test runner (an example the compiler must refuse).
