Here is an unfortunately very late paper providing further explanation for FI-064 (splicing).

Dear SG7 kidnapees, school-yard bullies, nerds, innocent bystanders, mountaineers,

we are going to have an 4FA SG7 telecon this Wednesday, on zoom:

sidenote: I need a scribe! ⚠️

We are going to discuss following DIS comments:

• https://github.com/cplusplus/nbballot/issues/1013 "make results of define_*_static functions structural, so it can be used directly as CNTTP"
• https://github.com/cplusplus/nbballot/issues/1006 "reflection of standard library entities" (mostly module related, it's reflection of using-declarations, which is currently ill-formed)
• https://github.com/cplusplus/nbballot/issues/1005 "disallow obj.[: private_reflection :] splicing of private members" (maybe it will go directly to EWG, depending on the response from author)

And these are all related papers, or papers proposing the fixes:

• P4414R0 (Ville's paper from mailing which proposed special context specific keyword)
• P4340R0 (Barry's paper from September mailing for c++26 providing generic and customizable solution) (there is a newer version here: D4341R1 (contains wording!)
• D4442R0 (Ville's paper summarizing SG7 Mattermost discussion, proposing future compatible way with P4340 without customization, only as opt-in/opt-out for structurality of types)
• P3687R1 (Dan's paper from Sofia which proposed way how to handle using-declaration, but we decided to make them ill-formed, in order to find a good solution later)
• There is no paper for the splicing (the third comment) AFAIK, this will be discussed in EWG week later in Búzios

I probably forgot some, so if anyone working on these please send them to this thread.

Also meeting notes will be edited here during the meeting: https://docs.google.com/document/d/1SQMMIlbtahNDE70SnKMfos6Mlf2sGPo0ryg0ANWjhFU/edit?usp=sharing

And I think that's all.
