The Sparrow language

[Andrei Alexandrescu via Digitalmars-d]

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.
