  Learning to make a Scheme interpreter in C

Next I tried to study parsing from his book but didn't find parsing to be as enjoyable. I then went to the dragon book , which I had found to be very dense the first time I flipped through it an year ago. This time I found it to be much more approachable, thanks again to what I had read in Nystrom's book. Precedence and associativity made more sense when I read it a second time. But it turns out that Scheme's grammar is really simple: Expr -> atom | '(' Expr ')', so I stopped reading and started coding.

It's barely usable because it has no GC, and I may have to rewrite it from scratch for implementing one. In the meantime I am thinking of doing a rewrite in Java, and then do part 3 from Crafting Interpreters, where the author implements everything in C.

Still very much a newbie, I welcome criticisms and directions for moving it forward.
