[PATCH] D140423: [WIP][clang] Add PrintingPolicy callback for identifying default template arguments

[Erich Keane via Phabricator via cfe-commits]

erichkeane added a comment.

A Class template instantiation SHOULD have its link back to the class template, and should be able to calculate whether the template argument is defaulted, right?  At least if it is the SAME as the default (that is, I'm not sure how well we can tell the difference between a defaulted arg, and a arg set to the default value).

I wouldn't expect a bool to be necessary, and I see `isSubstitutedDefaultArgument` seems to do that work, right?

So I guess I wonder why 'print the defaulted template args' isn't just a printing-policy?
