 ### variables and while
 
-`let` infers a variable's type from its initializer. an integer literal stays a plain word. `int i = 0;` writes the type explicitly. a local must be assigned on every path before it is read (locals are not zeroed); passing `&x` counts as initializing `x`, and an array or struct needs a full `{...}` initializer or `&agg`. the lifetime analyzer runs by default; the optional typechecker is enabled separately with `typecheck on;`.
+`let` infers a variable's type from its initializer. an integer literal stays a plain word. `int i = 0;` writes the type explicitly. a local must be assigned on every path before it is read (locals are not zeroed); passing `&x` counts as initializing `x`, and an array or struct is set once every field or constant-index element is written, by a `{...}` initializer, by `&agg`, or by a computed-index fill such as `a[i] = e` in a loop; reading a part that was written is fine. the lifetime analyzer runs by default; the optional typechecker is enabled separately with `typecheck on;`.
 
 `while` tests before entering the body. `i++` increments the variable, and `break` leaves the loop.
