One problem with Elerea experimental branch besides the update time control: the memo function. I can't understand when I have to call it and when I don't.
Just to know, have you been told of a language dedicated to reactive programming (even experimental)? I mean, not an embedded language just like Yampa is. 2010/5/24 Patai Gergely <patai_gerg...@fastmail.fm> > > IMO: For AAA game programming? Definitely not.
