The 10 Essential Features for the Future of C++ Libraries
summary
Claims ten essential (actually sixteen) missing language/library features and demonstrates them with a quantities-and-units library that exposes real issues: template-parameter kinds and universal/template/value NTP extensions enable readable unit syntax like km_per_h, but current structural NTP rules force public members and break encapsulation; ADL ignores non-type template arguments so quantity/units examples show ADL breaks requiring using declarations; C++26 accepts concept-template parameters and user static-assert messages; proposes compile-time emit/throw diagnostics, canonicalized type ordering, text parsing (scanlib) and CPS packaging to fix real pain points.
