The standard Go development team response to the "we must have dynamic 
library support in Go" is "you do not need it, use operating system 
processes and pipes". For operating systems that support many small 
processes, this is a most viable solution. UNIX and Linux are supposed 
to be such. Of course it helps that Go is channel and dataflow 
focused, so it is just a variation of the standard model.

Conversely CPython (and now by necessity PyPy, but not Jython or 
IronPython since it is irrelevant for them) trivially supports C and 
C++ for extensions. If D is to compete in this milieu, it is 
essentially to support C linkage dynamic linking on all platforms. I'm 
on Linux, it works for me :-) On the other hand if it doesn't work on 
Windows and OSX then perhaps it is broken?
