const /* see below */ ignore;
Ignore assignment
This object ignores any value assigned to it.

It is designed to be used as an argument for tie to indicate that a specific element in a tuple should be ignored.

Its type is unspecified, but should be able to support the assignment of a value of any other type (and ignore it).
