Me too 
I wanted to start simple as to be honest I wasn’t 100% sure I could get it to do this with any reliability but for this test case I have it working reliably. The key was working out the structure of the program spec and I had to give it the added hint that it should always use regular expressions. I noticed that it wasn’t always landing on a working function unless it decided to try using regular expressions. That hint seems to push it towards a more reliable solution…
Super early and lots of exploration needs to be done but it seems promising…
