To me that is fairly surprising behavior.  I would expect the compiler 
to look at *all* the values in the array literal and pick the type to 
use based on standard promotion rules ("integer promotions" and "usual 
arithmetic conversions" from http://www.digitalmars.com/d/type.html).

I.e. [1, 2, 3, 4.0] should be double[4], not int[4].

Just like 1+2+3+4.0 is a double and not and int.
