you need to contact Hal Finkel to allow your account on isocpp.org (which you need to have) to upload the paper there. You paper will be then part of monthly mailing, and then we can have a decision based on the paper.

Attached is a new paper addressing how the P2237/P2230 facilities might be expanded to be able handle the `Sum<T,U>` example discussed awhile back, and more generally subsume the capabilities of the "string-injection" approach, while avoiding its drawbacks.

Basically: `consteval {}` in more contexts (e.g. constructor initializer lists), and generalize the fragment syntax to allow for new fragment types (e.g. constructor initializer fragments).

I am attaching the markdown file as well for easier copying and pasting, e.g. to tweak the syntax of the examples for use in alternative proposals.

I haven’t yet figured out how to get a P number and put this on isocpp, but wanted to get this draft out before the weekend to give ample time for consideration before the upcoming meeting.

Thanks,

Dave
