One thing about that is that the type is being encoded into the 
name of the template parameter. Ideally, the type shouldn't be 
important, with the template constraints documenting anything 
noteworthy. With MyStruct, for example, I think 
MyStruct(Range)(Range r) would be better than the former, as it's 
more general. Then a template constraint such as 
if(isInputRange!Range) documents that the type must be at least 
an input range.
