In D, template parameters can take not only types, but almost any type

No, you can pass

I was reading the code for the DCV library and came across this
function:

Here is a shortened form:
[return type] rgbbgr2gray(bool isBGR, V)([run-time
parameters]){[implementation]}
and an example call:

Hi all,
Im porting some C++ code, which has a mess of a section that
implements prime number type id's. I've had to smother it to

that D provides is the better solution - Id rather not
reimplement that C++ mess ideally.
