static assert( isScalarType!(immutable(byte)));
static assert( isScalarType!(immutable(ushort)));
static assert( isScalarType!(immutable(int)));
static assert( isScalarType!(ulong));
static assert( isScalarType!(shared(float)));
static assert( isScalarType!(shared(const bool)));
static assert( isScalarType!(const(char)));
static assert( isScalarType!(wchar));
