/// @assertion If two or more extensions apply to the same member access, or if a
/// member of the receiver type takes precedence over an extension method, or if
/// the extension is imported with a prefix, then it is possible to force an
/// extension member invocation:
///
///   MyList(object).quickSort();
///
/// or if you don't want the type argument to the extension to be inferred:
///
///   MyList<String>(object).quickSort();
///
/// or if you imported the extension with a prefix to avoid name collision:
///
/// prefix.MyList<String>(object).quickSort();
///
/// The syntax looks like a constructor invocation, but it does not create a new
/// object.
///
/// If [object.quickSort()] would invoke an extension method of [MyList] if
/// [MyList] was the only extension in scope, then [MyList(object).quickSort()]
/// will invoke the exact same method in the same way.
///
/// @description Check that if several extensions can be applied to the same
/// member access, it's possible to force an extension member invocation if a
/// member of the receiver type tis imported with a prefix.
