--- Comment #1 from Michele Caini <michele.caini at gmail dot com> --- I notice that there is a flaw in the text. I expect this to compile and run with no errors, as it happens indeed: #include<cassert> int main() { assert((0 < 42) < 3); } From what I wrote, it would seem that I consider it an error. The actual issue is related to the fold expression.
