 Artur, check out Changelog and documentation,
 this was changed early this year.  Use [list] to
 help configure:

     A create a [list -par -e]

        * configure methods can be placed into a list to avoid
          ambiguity of "-". This character is used as a metachar to
          denote method names, but it has to be used in values as well.
          Example:
             Class Book -parameter {title author}
             Book b1 -title "--the title--" -author a.b.c
          has to be written as
             Book b1 [list -title "--the title--"] -author a.b.c
          Note, that XOTcl allows us to provide multiple arguments
          to methods called via configure. Note, that xotcl
          supports via this method calling methods with 0,
          1 or more arguments.
