I was busy, so just two comments about this long thread. Walter Bright:A lot of people do think duck typing is very important.
But it's better to add features to D because they are useful for D programs, and not because lot of people want "duck typing" in general. C#4 has added the "dynamic" keyword, its not named WizBang!, and its semantics is powerful and very well integrated with the rest of the language and virtual machine. This is how C# is better than D both in nomenclature style and in substance: http://msdn.microsoft.com/en-us/library/dd264736.aspx If you want you may use Google to find other better pages about the "dynamic" of C#4. ----------------------- Andrej MitrovicWhat's all this arguing about anyway? import std.conv : duck; alias duck as; alias duck adaptTo; Done deal.
That's false/misleading. I've once renamed "writeln" as "putr" in one of my code snippets and Walter answered me he didn't know what "putr" means despite the first line in the 10-lines long program was the import std.stdio: putr = writeln; "alias" is useful, but it's also misleading. Usually if you want your code to be easy to understand you have to stick with the default names that everyone else uses.
