Language Reference: Usual Arithmetic Conversions

[Morlan]

The following section from the Language Reference does not correspond to
the current dmd compiler (v2.052, Windows) behaviour:

"
Integer values cannot be implicitly converted to another type that cannot
represent the integer bit pattern after integral promotion. For example:

ubyte  u1 = cast(byte)-1;   // error, -1 cannot be represented in a ubyte
ushort u2 = cast(short)-1;  // error, -1 cannot be represented in a ushort
uint   u3 = cast(int)-1;    // ok, -1 can be represented in a uint
ulong  u4 = cast(ulong)-1;  // ok, -1 can be represented in a ulong
"

Both byte and short casts work all right.
