Oh, I am aware, but I didn't thought it would be necessary in 
this pace.

I don't consider to use any other language as long as I have a 
choice :-)

But in the end, my one short and beautiful solution

auto myRange = iota(start, end).map!foo;

changed into something quite klumsy:

auto myRange = iota(start, end).map!(x => 
foo(cast(ParameterTypeTuple!foo[0])x));

which I think is against the philosophy of D as it turns away the 
eye of the reader from what is really going on, especially if 
previous constraints ensured that start and end-1 are of the 
correct type :-(

But ok, still far, far better than what would be neccessary in C++
