//! A control-flow graph can be said to have “balanced flow” if the flow

//! and also equal to the sum of its out-edge flows.
//!
//! Control-flow graphs typically have one or more nodes that don't satisfy the
//! balanced-flow property, e.g.:
//! - The start node has out-edges, but no in-edges.
//! - Return nodes have in-edges, but no out-edges.
//! - `Yield` nodes can have an out-flow that is less than their in-flow.
//! - Inescapable loops cause the in-flow/out-flow relationship to break down.

//! Balanced-flow graphs are nevertheless useful for analysis, so this module
//! provides a wrapper type ([`BalancedFlowGraph`]) that imposes balanced flow
//! on an underlying graph. This is done by non-destructively adding synthetic
