I just got word about Sparrow (from its creator no less):

An interesting language that shares a lot of D's vision and
features. The languages differ in a few aspects: Sparrow has a
much more flexible syntax allowing a variety of custom
operators. (I happen to disagree that's a good thing as I
believe highly flexible syntax easily leads to transmission
noise code). On the plus side Sparrow has a smoother
integration of compile-time vs. run-time computation, which
makes it a bit easier to transition from one to another.
Another feature we could consider adding to D is a simple
definition of concepts as complex Boolean predicates. That's
essentially identical to isForwardRange etc. etc. but makes for
simpler use of these predicates.

Interesting. I've thinking about concepts too. Hopefully they
could come into D. Actually, I think concept and interfaces could
be combined into one feature. An interface is just a special case
of a concept, saying its implementer should have the matching
function signatures.
