Sounds about the same...  I remember it as "transitive const".
Looking at changeset 512, I can see only a few small changes:
* const after functions for const functions
* "static const" instead of just "const" for a few global constants

Is the 2nd one just code cleanup or does it have a deeper reason?

PS: It really is interesting to see just how little you've changed over the previous code.  If I remember right, the original framework caused grumblings about how hard it was to use string constants.  Since very little of that code has changed (I'm guessing), has this become any easier for developers?

PSS: I haven't used D 2.0 yet, so my questions may be ignorant.  It wasn't anything specific to D 2.0 except that Tango didn't work on it and gdc didn't support it.  Mac support was more important to me than cost support.
