 Previously, the elements of a collection expression targeting an `IEnumerable` implementation were assumed to be convertible to `object`, and converted only when binding to the applicable `Add` method.
 
 This additional requirement means that collection expression conversions to `IEnumerable` implementations are treated consistently with other target types where the elements in the collection expression must be implicitly convertible to the *iteration type* of the target type.
