language implementer sit down and define the run-time reflection 
mechanism. The full-assed way is to define compile-time reflection, to 
then allow people to define and refine run-time reflection mechanisms as 
libraries, in addition to many other useful libraries! It's like in the 
fish vs. fishing parable.

I agree but its like the stl vectors.  I'm unsure weather it just is 
easier to have that kinda thing in the language because it already has 
much of that information.  Also to write a reflection program that 
doesn't require wrapping each and every call you'd need to write a fully 
fledged D phaser which may become out of sync with the compiler.   I'm 
undecided on this matter.
