Limitations of C++26 define_static_array (quuxplusone.github.io)

• Lack of support for truly dynamic static sizing.
• Incompatibility with non-trivial object initialization workflows.
• Implications for memory-constrained safety-critical firmware.

"The upcoming C++26 'define_static_array' feature aims to simplify static storage management but faces significant hurdles in flexibility. This analysis highlights its inability to handle runtime-sized structures and complex initialization, which remains critical for high-assurance engineering in European industrial sectors."
