// Koru Standard Library: the `directives` part of compiler.kz — frontend-read
// compiler directives. Joined via `~part directives` in compiler.kz; merged
// into the compiler module at load.
//
// These tors are never dispatched: [norun] prevents auto-execution and the
// FRONTEND reads the invocation from the AST — discovered by parsing, not
// hardcoded. `requires` declares backend build requirements (build.zig
// generation is metacircular this way); `use` pins the backend itself to a
// minted compiler — it is consumed and stripped before backend emission, so
// the mint name never reaches the closure it selects.
~[comptime|norun] pub tor requires { source: Source }

// Pin the backend to a minted compiler: `std/compiler:use(my-compiler)`.
// `expr` resolves in the mint store; `hash` pins binary identity.
~[comptime|norun] pub tor use { expr: Expression, hash: ?string }
