Do you think D would benefit if you add this (or similar) feature to it?
Sean is working on a message passing (CSP) package for D. I'm not
convinced it needs to be a core language feature, though.

This is true.  After I created ParallelFuture (the lib w/ parallel foreach, map,
reduce), a friend mentioned that my model was pretty similar to the OpenMP 
model.
 I read a little about OpenMP and it really hit home how powerful a language D 
is,
given that I was able to implement something OpenMP-ish as a pure library, 
without
any modifications to the compiler.  The fact that message passing is built into
Go! makes me wonder if there's a reason why it can't be done well in a library.

Same could be said about dynamic arrays and hash tables/maps/dictionaries. They can be implemented as libraries (C/C++ approach).

The reason these data structures are built into languages like D and Python is probably the same reason that Go has channels and goroutines built-in.
