I love Prolog !
I only wrote an “hello world” with it, toyed a bit, and then when looking up documentation on the web, I found something strange and unknown to me called “Erlang”. That was some long time ago 
And now I’m here, so <3 Prolog
(More seriously it was kinda fun to play with!)
I’m a sucker for pattern matching, but I can hear the average developer yelling that it’s not readable. And that is properly why SQL is so heavily used.
Yeah some coworkers do not seem to want to take advantage of it … though on this forum “I cannot live without it now” seems to be shared by most people.
