Lightning Talk: Every Use Case of Colon and Ellipses in C++
summary
Claims to enumerate every use of colon and ellipses but instead composes a single C++ line that strings together global scope resolution, a lambda, a range-for, switch labels, variadic arguments, a binary fold over the dot star, immediately invoked lambdas, multiple inheritance, access specifiers, bitfields, member initializers, label attributes and C++26 pack tricks. The demo uses real grammar (namespace::, ..., .* , operator[], using-directives) and constructs a line with dozens of dots that compiles and exercises all those corner cases.
