//! if assigning anything different from `value` to `place` turns the `SwitchInt`
//! into `Goto { target }`.
//!
//! In this file, we denote as `place ?= value` the existence of a replacement condition
//! on `place` with given `value`, irrespective of the polarity and target of that
//! replacement condition.

//! When we find a fulfilling assignment, we record a `ThreadingOpportunity`.
//! All `ThreadingOpportunity`s are applied to the body, by duplicating blocks if required.
