Research direction

The issue requests simd_mask constructors and an accessor for BitInt, plus a paper for C++, and identifies P3348 as a dependency. Start by locating the BitInt and simd_mask implementations and their tests in the repository; done requires agreed API behavior, coverage for the new operations, and the paper write-up.

Written by the indexing model from the issue text.

Description

C++29 extension enhancement

Also write up as a paper for C++. This relies on P3348 to pull C23 into C++26.
