> The idea of defaulting to an optimizing mode has come up before. Sorry, maybe I made my statement not clear enough: Of course it is fine that default compiler mode is to use runtime checks and do not use -d:danger. @didlybom asked to generate an automatic main function so that newcomers making a benchmark would get good results. But generally these newcomers also forget to compile with -d:release, and also these newcomers often use too many ref objects, too many string allocations and other slow stuff.
So the recommendation is: Before making benchmarks or videos read a tutorial.
