Module-level `fn`, `struct`, `const`, and `interface` declarations now accept an `export` modifier, which is mandatory to make them reachable from other source files or compilation units. Items inside a `program` block cannot be qualified with `export` since they are already implicitly public. Accessibility rules are checked in the type checking phase. This is a breaking change, as previously unqualified function declarations are now private by default. `export` was chosen instead of `pub` because: 1. it is desirable to minimize confusion with existing and future uses of `public`/`private` 2. access rules are more analog to Javascript than Rust (no `mod`, relative paths) 3. we already have an `import` keyword
