Yampa is a domain-specific embedded language for the programming of hybrid (discrete and continuous time) systems using the concepts of Functional Reactive Programming (FRP). Yampa is structured using Arrows, which greatly reduce the chance of introducing space- and time-leaks into reactive, time-varying systems.
Yampa was originally developed by the Yale Haskell Group based on the original idea of Conal Elliott's Fran.

Switches
Each switch comes in two different flavors:
- immediate: switch to the new behaviour immediately and also calculate the return value based on the new behaviour.
- delayed: return the value based on the old behaviour, but use the new behaviour afterwards. To use delayed switch prefix the switching functions with the letter 'd', f.e. 'drpSwitchB'.
