 reparse and the parse label:

  Reparse and the parse label "parse>" are important for ensuring that
  all shift-reductions take place. .reparse should be used in a 
  testblock, where the test text is a series of tokens in the form
   "token*token2*token3*"
  reparse basically jumps back to the parse label (implemented as 
  "parse>" currently). 

  The example below corresponds to 2 grammar rules:
    1. expressionset <- expression expression
    2. expression <- term operator term 

  If the 2nd test is matched by the workspace ("term*operator*term*")
  then the 2nd reduction will take place. This may leave the stack
  in the state "expression*expression*"
  which means 

  You may think that a simple solution would be to reverse the orders
  of the 2 blocks and in this case that may work. But in many types
  of grammars it will be impossible to find an order in which all
  necessary reductions will take place: hence .reparse
