> Everybody should build code at this level from day 1. On the project I run, the CI will reject your code in CR if it doesn't compile under two different compilers with all but a handful of warnings turned on as errors, runs and passes tests, and passes various linters, including a check for undocumented types, variables, parameters and return values. IMNSHO, every project should be like this. Once it's setup, it's a breeze and doesn't impede development speed at all.
