It's just because array literals are only supported at this time for 
strings. (Your code might work in DMD 2.0).

If you change the definitions to
const char [] str = x"01 02 03";

template aphasht( char [] T)
{
	const uint aphasht = ...
}
(changing returns to const aphasht).

it would work with

writefln( "aphasht(str) = %X", aphasht!(str ) );
