// FIXME: Currently the `everybody_loops` transformation is not applied to:
// * `const fn`, due to issue #43636 that `loop` is not supported for const evaluation. We are

// ambitious form of the closed RFC #1637. See also [#34511].

/// Replaces function bodies with `loop {}` (an infinite loop). This gets rid of
/// all semantic errors in the body while still satisfying the return type,
/// except in certain cases, see below for more.

/// This pass is known as `everybody_loops`. Very punny.

/// As of March 2021, `everybody_loops` is only used for the
