Classes inheriting trait `Show` can test their member methods using the notattion 'meth(arg_1, ..., arg_n), where `meth' is the name of the method and `arg_1,...,arg_n' are the arguments. The only difference to a normal method call is the leading quote character ('). A quoted method call like the one above will produces a legible diagnostic to be printed on Console. It is of the form meth(arg_1, ..., arg_n) gives where is the result of evaluating the call.
