The implementation of conceptually continuous signals in functional reactive programming (FRP) is studied in detail. We show that recursive signals in standard implementations using streams and continuations lead to potentially serious time and space leaks under conventional call-by-need evaluation. However, by moving to the level of signal functions, and structuring the design around arrows, t...
