static assert( isSomeChar!char);
static assert( isSomeChar!wchar);
static assert( isSomeChar!dchar);
static assert( isSomeChar!(typeof('c')));
static assert( isSomeChar!(immutable char));
static assert( isSomeChar!(const dchar));
//Non char types
static assert(!isSomeChar!int);
static assert(!isSomeChar!byte);
