Answer:

Binary Scope Resolution Operator

Explanation:

The :: (scope resolution) operator is used to get hidden names due to variable scopes so that you can still use them. The scope resolution operator can be used as both unary and binary. Fortunately, in this context we're not dealing with hidden contents; thus the Binary applies better than the Unary.
