The dynamic extent of a procedure call is the time between when it is initiated and when it returns. In Scheme,
call-with-current-continuation(section on control features) allows reentering a dynamic extent after its procedure call has returned. Thus, the dynamic extent of a call might not be a single, continuous time period.This sections introduces parameter objects, which can be bound to new values for the duration of a dynamic extent. The set of all parameter bindings at a given time is called the dynamic environment.
