  Returns:
    true if there is another match

### start

  Returns:
    the start of the current match
  Throws:
    `IllegalStateException` - if there is no current match

### end

    int end()

  Get the last symbol index that matches the pattern.

  Returns:
    the end of the current match
  Throws:
    `IllegalStateException` - if there is no current match

### group

    SymbolList group()

  Get the matching region as a SymbolList.

  Returns:
    the matching symbols
