C++ Cryptozoology - A Compendium of Cryptic Characters
summary
Covers concrete C++ oddities: shows abominable function types — syntactically valid function types that only make sense as class method declarations — and explains why they compile. Demonstrates a real undefined behavior example: a global function pointer initialized to null, later invoked, provokes UB that made GCC emit code erasing a drive; mentions using UBSan to catch such cases. Explains template duck‑typing, upcoming concepts for constrained templates, and the C++20 three‑way comparison (operator<=> = default) generating efficient memberwise ordering.
