Hi Imran + Tomas, in addition to Tomas' perfect explanation, let me add one note to:

That shouldn't be > that hard. There is a way to switch the Lisp-level 'read' function to a kind of "low-level mode", by calling it with one or two arguments (explained in the reference). In that case, 'read' returns atoms (numbers, internal and transient symbols) but not complete s-expressions. Parentheses and other meta-characters are simply returned as transient symbols and can be conveniently processed. This makes it quite easy to write a customized reader. For example, the JSON "library" (http://rosettacode.org/wiki/JSON#PicoLisp), mentioned earlier in this thread, makes use of that.
