   1 In process/stepA.gliffy, add inc and remove *gensym-counter*.
   2 Then refresh the .png files.

   6 General:
   7     - add chat bot for #mal
   8     - move tokenizer.mal and reader.mal from malc to ./lib directory
   9
  10     - Finish guide.md
  11         - mention that identifier names are suggested. some have run
  12           into collisions with READ,EVAL,PRINT in case insensitive
  13           languages
  14         - simplify: "X argument (list element Y)" -> ast[Y]
  15         - more clarity about when to peek and poke in read_list and
  16           read_form
  17         - tokenizer: use first group rather than whole match (to
  18           eliminate whitespace/commas)
  19
  20 All Implementations:
  21     - regular expression matching in runtest
  22     - add re (use in rep) everywhere and use that (to avoid printing)
  23     - fix stepA soft failures: lua matlab miniMAL perl racket
  24
  25 Other ideas for All:
  26     - propagate/print errors when self-hosted
  27     - redefine (defmacro!) as (def! (macro*))
  28     - Fix/implement interop in more implementations
  29
  30     - metadata on symbols (as per Clojure)
  31     - metadata as a map only. ^ merges metadata in the reader itself.
  32       Line numbers in metadata from reader.
  33     - protocols!

  36     - namespaces
  37         - environments first class: *ENV*, *outer* defined by env-new
  38         - namespaces is *namespaces* map in environment which maps namespace
  39           names to other environments.
  40         - def! become an alias for (env-set! *ENV* 'sym value)
  41         - Namespace lookup: go up the environment hierarchy until
  42           a *namespaces* map is found with the namespace name being
  43           looked up. Then the symbol would be looked up starting in
  44           the namespace environment. Need protocols first probably.
  45
  46     - multi-line REPL read
  47     - loop/recur ?
  48     - gensym reader inside quasiquote
  49     - standalone executable

  73     - TCO using seq/bang patterns:
  74       http://stackoverflow.com/questions/9149183/tail-optimization-guarantee-loop-encoding-in-haskell
  75     - immediately exits mal/clojurewest2014.mal ("\/" exception)
  76
  77 Java:
