Hi, and here the next question... :-) I try to assimilate Python's `StringIO' class to Ruby. Now I want to derive `StringIO' from `IO'. So that StringIO.new.is_a? IO But now my problem is, that `IO#new' want to have a filedescriptor as parameter. But I cannot deliver such one. What I need, is to write a `StringIO#new' that doesn't need to call `IO#new'! Could someone give me some advice? Thanks in advance, \cle
