Yeah. How little do I have to know to be able to do a little? It really matters. But then, it also matters that it not trap you. It's easy to only have to learn a little when a little is all there is. But you don't want to use a language like that for something major, because it won't do enough for you. So what you need is something like what the UI people call "progressive disclosure". Are there any languages that do that well?
