I’d find trying to create a perfect program pre-compile and pre-unit test horribly inefficient. OTOH I think programmers should strive not to lean on the compiler to find silly errors: so build up working memory of syntax etc. and slow down to double check the code you wrote. But having that compilation and unit test loop - or even a repl - I could code as efficiently without it.
