in thread perl/Tk Entry validation

Actually the question is not really if it is NECESSARY to pass some arguments to the validate command but if it is POSSIBLE - just as it is done in the case of any other command using a subroutine reference with arguments in a list. Remember I want to set the boundaries as parameters of the validation process.

    If you use the annonymous array syntax, the listed arguments will be prepended to the standard argument list.
