From: tran55555@... (Email55555) Date: 2002-08-30T06:13:39+09:00 Subject: Newbis question - Pre-defined classes & modules I am new in Ruby. Do not like to check the C source code. I like to know the Pre-defined classes and modules, are they all writen by C or some are implemeted by Ruby language itself ? (For example the Enumerable, it is esay to implement by Ruby itself) Thanks.
