At the moment, we need this. The TypeInfo member that contains the 
initialization data was called init. It was very recently switched to 
initializer, but we cannot get rid of that alias for a few releases.

After that, I think we can consider removing that ability from the language.

One thing that just occurred to me though, Objective-C makes use of the 
init function quite a bit. I wonder how getting rid of init as a 
customizable member would affect that.
