v0.6.0

Breaking

• renamed the auto-generated list names with better numbering. e.g.

  N
  	::= A? B# C;
  

  transforms to

  N ::=
  	|   N__0__List C
  	| A N__0__List C
  ;
  

  not

  N ::=
  	|   N__1__List C
  	| A N__1__List C
  ;
  

  (previously, the counter was incremented on the ? operator)

Non-Breaking

• Kleene star * operator used to have its own semantics. Now it shallowly maps to a +? combo. For example A* is now shorthand for A+?. This is an internal optimization only and makes no outward-facing changes.
