--- Some guidelines for compiling functions and scopes.
---
--- 1. use env.beginScope/env.endScope properly;
--- 2. in each scope traverse the definitions twice:
---    a. first, add all bindings into symbolic state,
---       using end.addVar/env.addFunction;
---    b. do not forget to generate GLOBAL instructions for
---       top-level variable declarations;
---    c. on the secord traversal add functions themselves for
---       future code generation (use env.rememberFunction).
--- 3. the overall flow for codegeneration:
---    a. generate the code for thetopmost expression (the progrman itself);
---    b. take list of nested functions definitions via env.getFunctions and
---       generate the code for each function;
---    c. repeat b. until no function definitions appear.
--- 4. when compiling functions, do not forget to create proper
---    environment (use env.beginFunction/env/endFunction) and register arguments
---    (use env.addArg).
