Plans for V2

[gaborcsardi]

• Use comments, if possible. Comments look nicer, and they really have zero overhead. (It might not be possible, as it probably requires re-parsing the code, especially if CRAN will include the source refs without the parse data.)
• Assertions WISH: Near-zero overhead assertions #32
• Re-think debug levels
• Tagging
• Turn debugging on-off using:
  • Package names
  • Debug levels
  • Tags
  • Function names
  • File names
  • Etc ???
• C/C++ support
• Formatters, defaulting to glue
• JSON (?) logging, basically some way to log composite objects that can be inspected
• Logging to a pipe or fifo, to be able to inspect, browse while the logging is active
• Interactive log browser, an HTML widget would be nice.
• Handle repeated log messages better
• Ability to stop in a browser(), if the debug message is active. We probably just need to
  make sure that something like

  ## !DEBUG { if (cond) browser() } blah
  

  works
