Hi all, Having taken a short break from my profiling project, I updated my little FRP library called Elerea [1] along with the runnable example programs [2]. The interface was changed into a monadic-applicative hybrid that distinguishes stateful and stateless combinators for safety reasons. Since this is a major change, this release bears a new major version number. Most importantly, the latcher was removed due to various practical issues, and it is replaced by much better behaved stateless higher-order constructs. The library is capable of handling arbitrary higher-order signals, e.g. dynamic collections of signals, as shown by the renewed breakout example (which used to cheat so far by treating the state of the brick collection as a single value). I intend to write some tutorials later, but feel free to experiment until then.
