Templatey signatures.

Understanding template specialization and method overload resolution in C++

This easy C++ question tests your grasp of how the compiler resolves method calls when templates and overloads interact. It requires you to reason about template instantiation, specialization rules, and the order in which the compiler considers candidates during overload resolution.

The question uses a concrete example to probe whether you understand the subtle rules that govern when two method declarations conflict (causing a compilation error) versus when they can safely coexist. This is foundational knowledge for writing robust generic C++ code and avoiding hard-to-debug template instantiation failures.
