<DL>
<DD>Compute the closure of the set using the LALR closure rules.  Basically
  for every item of the form: <pre>
    [L ::= a *N alpha, l] 
  </pre>
  (where N is a a non terminal and alpha is a string of symbols) make 
  sure there are also items of the form:  <pre>
    [N ::= *beta, first(alpha l)] 
  </pre>
  corresponding to each production of N.  Items with identical cores but 
  differing lookahead sets are merged by creating a new item with the same 
  core and the union of the lookahead sets (the LA in LALR stands for 
  "lookahead merged" and this is where the merger is).  This routine 
  assumes that nullability and first sets have been computed for all 
  productions before it is called.
