Modern techniques for keeping your code dry
summary
Shows how to build zero-cost abstractions in modern C++ using fold expressions, constructor template argument deduction and deduction guides, lambda factories, tuple+apply and small higher-order helpers to write readable predicates like any_of/each_of. Claims the generated assembly is identical across clang GCC and MSVC, so no runtime cost. Delivers working code that builds readable checks, a bind-right helper and tuple-as-lambda tricks, but notes unpleasant repetition for conditional noexcept and explicit return-type SFINAE that currently force macros or awkward boilerplate.
