[antlr-interest] string interpolation

I've just found this code in the TokenStreamSelector class:

<snip src="TokenStreamSelector.cs">
  public virtual Token nextToken()
   // return input.nextToken();
   // keep looking for a token until you don't
   // get a retry exception.
    for (; ; )
     return input.nextToken();
    //catch (TokenStreamRetryException r)
     // just retry "forever"

The java version of the method catches TokenStreamRetryException only. Is there any special reason why the C# version is not doing the same?

Uncommenting the catch (TokenStreamRetryException) solves my problem.

BTW, this is the second change I apply to my private copy of the C# runtime library... Whom I can send them to?

  I'm building a very simple parser that recognizes (and interprets) simple programs such as:

      a = 5+3
      b = 102-5
      print "a: ${a}, b: ${b}, a+b: ${a+b}"
