Lightning Talk: Into the Lambdaverse — The Beginning
summary
Shows an actual code experiment: an immediately-invoked lambda that does ++n in an immediately-invoked lambda and variations that toggle mutable vs const capture interaction. Captures by value, default capture with =, and init-capture produce conflicting compile results; the presented tests compile the mutable case, reject the plain case, then surprisingly accept a specific init-capture form. References specific C++ standard paragraphs and multiple compilers agree, leaving the standard/implementation mismatch unresolved.
