num::call_site

Defined in header <core/call_site.hpp>

struct call_site;

A source location that records where a function was called.

Under GCC through 14, std::source_location::current() as a default argument of a function template records one location per specialization. A non-template constructor's default is evaluated at each call, so the templates take a call_site defaulted to {}.
