-"""The optimizer tries to constant fold expressions and modify the AST
-in place so that it should be faster to evaluate.
-
-Because the AST does not contain all the scoping information and the
-compiler has to find that out, we cannot do all the optimizations we
-want. For example, loop unrolling doesn't work because unrolled loops
-would have a different scope. The solution would be a second syntax tree
-that stored the scoping rules.
