//! This is a fixture we use for tests that need lang items.
//!
//! We want to include the minimal subset of core for each test, so this file
//! supports "conditional compilation". Tests use the following syntax to include minicore:
//!
//! //- minicore: flag1, flag2
//!
//! We then strip all the code marked with other flags.
//!
//! Available flags:
//! sized:
//! unsize: sized
//! coerce_unsized: unsize
