I tend to avoid writing complex code in production for various reasons. Of course if I ask copilot to write an new complex algorithm using my unique data structures in one try, it will not generate perfect code. But usually I try to go slowly line by line in these cases. Copilot shines to write the boring easy code and help you line by line, but it’s not there yet for advanced unassisted programming.
