+1. This is the approach I'm currently taking. I tried starting with books and tutorials but felt I wasn't learning much just being spoon-fed code and copy+pasting. I think it's much more illuminating to attack the problem with a beginner's mindset and work it out for yourself, at least up to a point (to start I'm working on implementing a small subset of Scheme). If I occasionally get stuck I'll peek at a book just enough to get un-stuck. I'm having a blast with it and learning a ton. Once I get tired of implementing language features I'll probably start from scratch and follow a book the second time through. For me it's often easier to absorb problem-solving concepts if I've attempted the problem myself before.
