P2964R0: Allowing user-defined types in std::simd

2024-03-22 SG6 Minutes

Chair: Matthias Kretz

Champion: Daniel Towner

Polls

POLL: A simd<UDT> should always mirror the complete set of operators of
UDT independent of special implementations of the basis functions. This
implies falling back to a loop over scalar operator calls. (Open to reversal if
experience convinces us differently.)
