 <p>In practice, the SourceLocation works together with the SourceManager class
-to encode two pieces of information about a location: it's spelling location
-and it's instantiation location.  For most tokens, these will be the same.  However,
-for a macro expansion (or tokens that came from a _Pragma directive) these will

-location where the token was used (i.e. the macro instantiation point or the 
-location of the _Pragma itself).</p>
