It's very early days for Chapel at the moment, but I don't really 
see it as being remotely comparable to D or even Julia, it's much 
closer to a DSL than a general purpose language. That's by no 
means a bad thing, it seems like it could be a very useful tool 
in a few years, but it's never going to completely substitute for 
the likes of Python, C++ or D even for purely scientific 
programming. I'm also a bit concerned about how limited the 
compile time facilities seem there at the moment, but I guess 
we'll just have to wait and see how it develops over the next 
couple of years.
