The coolest thing copilot or whatever did in vscode for me was generating a block of boost::regex code for c++. I started typing it, and it generated a block of 10 or so lines that would have been 10 minutes or so of deciphering boost docs, writing a simple test, failing, recompiling, etc. There is nothing worse than dealing with regexes, and it wrote the function for me, and then I wrote tests and verified it did what I needed.

Then copilot was blocked at work. ¯\_(ツ)_/¯
