This compiles with no errors nor warnings (dmd 2.060alpha):


struct Foo(T) {}
Foo!void f;
void main() {}


While a C++ compiler as G++ 4.7 gives:
error: ‘void’ is not a valid type for a template constant parameter

On IRC someone has said this is a feature of D. If this feature is present in D
docs then I suggest to make such note a bit more evident and to explain a bit
how this feature is useful. I think this is useful for C++ programmers.
