Exactly, the "you dont have" part lasts until the first error message and then it's 10 feet of stl template instantiation error avalanche. And stl implementation is really advanced c++. Also, a lot of "modern" code cannot be debugged at all (because putting in a print statement breaks constexprness) and your only recourse is reading code. This is in big part also because of committee, that prefers hundred-line template monster "can_this_call_that_v" to a language feature, probably thinking that by not including something in language standard and offloading it to library they do good job.
