<p>The <code>source_location</code> class represents certain information about the source code, such as file names, line numbers, and function names. Previously, functions that desire to obtain this information about the call site (for logging, testing, or debugging purposes) must use function-style macros so that predefined macros like <span class="t-lc">__LINE__</span> and <span class="t-lc">__FILE__</span> are expanded in the context of the caller. The <code>source_location</code> class provides a better alternative.
