Right, you might need method names containing "!" and "?" characters or operator method names like "===" etc. The constants are also easier to setup in a library that's using the initializers. The initializers are no magic though. The generated initializer for a given library is invoked by load_assembly method in file.rb that you require to load the library. For example, enumerator.rb:
load_assembly 'IronRuby.Libraries', 'IronRuby.StandardLibrary.Enumerator' RubyMethod/RubyClass/RubyConstant/... attributes declare what the generated initializers should do. They are not used at runtime. You can write your custom code that builds Ruby classes and registers them to the runtime using APIs on RubyModule/RubyContext. You could then invoke the code from your_lib.rb file that you require to load your library.

For example, if you wanted a class constant, you couldn't just declare a C# "const" variable as that would be appdomain-wide and also read-only. So you have to tag it with "RubyContantAttribute", right?

But that's not the case, so we use initializers. As for the scenarios you mentioned: 1. Porting Ruby native extensions Why not to write them in Ruby with calls to .NET Framework assemblies? Is there anything that makes this difficult? 2. Create an IronRuby library in C# in order to improve performance of a certain operation Couldn't you write the parts whose perf matter in C# code that doesn't have all the Ruby bells and whistles and keep your library written in Ruby?
