ok, i remove them.

distinguishing mandatory spaces is not easy across languages

I thought about tagging non-mandatory spaces, but there are too many

about counting tokens:
- variables names are the same for each snippets, so no pb
- library function names difference in length can be quite important.
  should System.Console.WriteLine be considered as 1 token? 5 tokens?
  whereas scheme's "read-string!/partial" or "date->time-monotonic" be
  1 token ?

ok, i replace gcc with tcc

I would say debuggers. A debugger with full REPL power is nice. 

how do people debug in python? do they really do 
% python /usr/lib/python2.2/pdb.py prog.py
