I think an interesting question to ask here is "the source location of
what exactly?".
The value of the source location is always the same, yes, but its
meaning is different depending on if the token in question is an
argument or not.
When the token is not an argument, then yI is a source location for *that*
token in the macro definition. It's then the spelling location for the
token in question.
When the token is an argument, then yI is a source location for
*another* token. Namely, the parameter for that argument. Not
necessarily the spelling location for the token we are observing.

Yes, but it's always a locus of the observed token.
Would LRK_MACRO_DEFINITION_LOCATION be better then? :-)
