It does happen to have some Perl-likeshortcuts, but I view those as training wheels for folks coming to Rubyfrom Perl.I personally like the style and dynacism of Ruby. For instance, to declarea class that inherits from another class you simply have:class Foo < Bardef myMethodFile.new ("test.dat", "w") { |f| f.puts "Hello world!"}endendHere, class Foo inherits from class Bar. Except that class Bar is just anexpression that returns a Class object. In this case it's a constant, butyou could just as easily have:class Foo < someMagicRoutine(someArgument, somethingElse)File is a real object, we'll call open on it. The opened file object ispassed to the block as local variable f, where we can call puts (named asin libc) to put a string to the file. At the conclusion of the block,the file is closed automatically.Doesn't look much like Perl to me. Oh, and that's just one way to use files -- you don't have to use them in a block, but I find ithandy to make sure I've really closed a file :-)/\ndy--Andrew Hunt, The Pragmatic Programmers, LLC.Innovative Object-Oriented Software Developmentweb:http://www.pragmaticprogrammer.com email:andy at pragmaticprogrammer.com--Books by Andrew Hunt and David Thomas: "The Pragmatic Programmer" (Addison-Wesley 2000) "Programming Ruby" (Addison-Wesley 2001)--
