Given that D templates are way, way, /way/ more powerful than C++
templates, what's to stop you?

The fact that D structs are way way /way/ more wimpy than C++ structs. :-)

But that's changing.

Also that argument deduction in D templates isn't very complete.  Nested 
types mess it up, like Mike Parker found just recently in another thread.

Lack of template overloading and of overloading across modules can cause 
headaches too.

But anyway some people made a "Blitz++-like" library for C#.  It just 
requires that you use various shades of "unnatural" syntax like 
expr.AssignTo(r) instead of r = expr:

D could at least do better than that, I'm sure.
