Except when token concatenating a ## b and stringifying # a.

As an aside, should there be spaces on either size of the ## concatenator?  The current code mostly doesn't -- which means it sometimes does.  My feeling is use whichever is clearer but we might want to codify this as yes, no or submitter decides.

Likewise, should there be a space after the # stringifier?  Existing code doesn't, apparently without exception.  I'm pressed to think of a case where having a space increases clarity but I'm sure some exist.
