There is very little runtime reflection capability. The position has 
always been that you can *build* runtime reflection given compile-time 
reflection.

object has rtInfo, as Adam says, which is built to be able to extend 
TypeInfo. But at the moment, it's not used for anything, and likely will 
stay that way for a while.

Note, you CAN build runtime reflection using mixins, but other than 
rtInfo, there's no way to instrument modules you don't control. Even 
that's a high bar, since you would then have to have a modified druntime.
