Choreographic Programming is an emerging paradigm for correct-by-construction concurrent programming. However, its applicability is limited by the current lack of support for reusable procedures. We propose Procedural Choreographies (PC), a choreographic language model with full procedural abstraction. PC includes unbounded process creation and name mobility, yielding a powerful framework for writing correct concurrent algorithms that can be compiled into a process calculus. This increased expressivity requires a typing discipline to ensure that processes are properly connected when enacting procedures.
