I don't know why but when using a template union with a static

ubyte[] toBytes(T)(T from) if (!is(T == const))

void main(string[] args)
{
writeln(fromBytes!uint(toBytes(34u)));// should print 32 but
prints 1244564
}
why dose it print 1244564 the array is static size so why is
it acting like bytes is a pointer not a static array?

endianness should not be an issue since I'm not changing machines
and using static array unions is a common way to convert to bytes
in D.
