Fair point, but a few years ago, I had no experience in Lisp, Python
or Ruby. Not even Haskell nor ML. I was a provincial C/C++ user :)
I'm cured of that.

Anyway, do many languages use MOPs ? I thought CLOS/MOP was more
one-of-a-kind curiosity for Common Lisp ? I know Python has
metaclasses, but until know I did not see them as a meta-object

So yes, D is still behind Lisp as far as crafting code is concerned
(but what language isn't?), but I think the recent increase in power
for CTFE opened new vistas and we are beginning to see the effect of
that (cue std.regex).

And, we are not *that far* from being able to encode user-defined AST
transformations on D source code, so that people will be able to
define their own syntax.
