I'm unaware of much code that uses TypeInfo.xtostring to print anything.   
write[f][ln] doesn't, and I don't think std.conv.to does either.

In other words, killing the "specialness" of toString doesn't mean killing  
toString methods in all structs.  What this does is allow us to not worry  
about what you annotate your toString methods with, it just becomes a  
regular method.
