| Let's say your string is in the variable called string.
| 
| (eval (read-from-string string))
| 
| This will evaluate exactly one expression from the string.  You'll have
| to do something more (probably with subseq or something) to read and
| evaluate multiple expressions from a string.

  note that read-from-string returns two values, the secondary of which is
  the position from which you could continue to read from the string.
