A control flow operator that captures the current execution context as a first-class continuation object, allowing programs to jump to that point later. It provides the ability to implement complex control structures like exceptions, coroutines, and backtracking.
Introduced in Scheme in the 1970s, often abbreviated as call/cc. The term combines 'call' (invoke) with 'current continuation' (the computation that would normally happen after this point). It represents a fundamental operation in continuation-based semantics, making the implicit control stack explicit and manipulable.
