Time for std.reflection

[Kapps]

I agree with most things proposed, however I am not a fan of the 
idea of mixing in runtime reflection info. Many times, you want 
reflection info from a type that is not your own, and thus I 
believe reflection should be generated by specifying a type. More 
importantly, a method should exist for recursively generating 
reflection info.

Also, I'd like to see a hierarchal approach to reflection data. 
The main advantage to std.reflection would be being able to use 
it at run-time, at which point we can't simply rely on templates, 
and instead if we want to store something we must rely on a base 
type. I think the best approach would be a hierarchal system 
where all reflection data derives from MemberInfo. My ideal API 
would like something like:
