Following on from the part couple of days of Rediscovering Perl, I was honestly surprised how much I'd forgotten after being retired for 3 years! 30+ years of getting paid to do #Perl every day, then .. nothing. Now I suddenly needed to hit the ground running again and found it challenging. The best bit though is that I saved nearly all the code I'd written and was able to instantly refer to working code I'm also really impressed that I can run all this stuff on small, portable devices - how times have changed!
