The agenda is:

  * P3412R3: String interpolation <https://wg21.link/p3412r3>.
  * P3951R0: String Interpolation with Template Strings
    <https://wg21.link/p3951r0>.

SG16 previously reviewed *P3412R1 <https://wg21.link/p3412r1>* during
the 2025-02-26 SG16 meeting
<https://wiki.isocpp.org/2025_Telecons:SG16Teleconference2025-02-26>.
Concerns raised then included interaction with the preprocessor, the
phases of translation, handling of escape sequences, standalone
usability, and integration with std::format(). Bengt will present a
brief overview of the proposal and the updates in the new revisions
intended to address prior SG16 review feedback.

*P3951R0* is a new paper courtesy of Barry that offers an alternative
perspective on string interpolation that makes different tradeoffs
relative to P3412R3.

Please try to set aside time to read both of these papers before the
meeting as there are many details to consider. Spend some time
considering possible future use cases (from an SG16 perspective) and the
ability for each design to evolve to satisfy them.

I don't expect discussion on these papers to conclude at this meeting.
Plan for 30 minutes of presentation and clarifying questions for each
paper. We'll then proceed with general discussion. Ideally, discussion
would lead authors towards a unified/merged design or a determination
that one proposal or the other is objectively better suited to desired
and anticipated uses. If consensus for a single design fails to emerge,
then we'll focus on understanding the points of contention with a goal
of ensuring LEWG is well informed of the relevant tradeoffs.

Tom.
