Thanks, done.

If I create a new project my typical approach is:
a) write the tests and function skeletons
b) implement them without much speed tuning (readability is better)
c) If all test passes let it settle, then benchmark, profile and
optimize for speed. (active)

No, never tried. Philip wrote there is a JSON implementation in io package.
