Re : [Haskell-cafe] Improving event management in elerea

http://hpaste.org:80/fastcgi/hpaste.fcgi/view?id=8159

and I have two questions.

1) my event function (line 79) returns a new signal and takes 3 arguments : an initial signal and a Bool signal which triggers when to apply the transform function given as a third argument. The body of the event function uses two calls to the sampler function. Is it possible to write this body with a unique call to sampler ?

Second question solved with event ini b f = mdo let gs = generator eb $ (flat.f) <$> s' eb <- edge b s' <- sampler <$> storeJust ini gs s <- sampler <$> storeJust s' gs return s but I still can't answer my first one (couldn't this function -or its improvement- be part of the library ?)
