| For an operation of the form `x << count` or `x >> count`, binary operator overload resolution ([§12.4.5](expressions.md#1245-binary-operator-overload-resolution)) is applied to select a specific operator implementation. The operands are converted to the parameter types of the selected operator, and the type of the result is the return type of the operator. | ||
| Dynamic binding uses values of type `enum System.Linq.Expressions.ExpressionType` to communicate binary operator kind to the runtime binder. As there is no enum member specifically representing an unsigned right shift operator, dynamic binding for `>>>` is not supported. | ||

| For an operation of the form `x << count`, `x >> count`, or `X >>> count`, binary operator overload resolution ([§12.4.5](expressions.md#1245-binary-operator-overload-resolution)) is applied to select a specific operator implementation. The left operand is converted to type `T`, where `T` is the first of `int`, `uint`, `long`, and `ulong` that can fully represent all possible values of the operand. The operation is then performed using the precision of type `T`, and the type of the result is `T`. |

Should nint and nuint be included here?

no. This is the integer-promotion rule; predefined >>> operators on nint/nuint (already listed) match directly when the operand is nint/nuint. Promotion targets stay int/uint/long/ulong because those cannot uniformly "fully represent" platform-sized nint/nuint. Text is consistent with the rule used for <</>>.

Update some of the grammar, and a few normative rules
