To keep both the compiler and programmers sane, D templates don't 
perform implicit type conversions. This sometimes is not handy, 
but on the whole saves from a large number of troubles.

So you can write (D V.2.066):

Vector!ubyte(ubyte(1), ubyte(1), ubyte(1));

Or you can create a little helper function that makes that code 
more DRY.
