Easter egg in SWI-Prolog

Iโ€™m using: SWI-Prolog version 8.1.9.

I just had a a laugh-out-loud moment with SWI-Prolog. I accidentally typed MAKE instead of make in the console and look what I found:

แŒ€42 ?- MAKE.
% ... 1,000,000 ............ 10,000,000 years later
% 
%       >> 42 << (last release gives the question)

To the author of this funny message: "Thanks for all the fish! :slight_smile:

Actually itโ€™s any time you enter a variable at the command prompt. Thatโ€™s even funnier because I guess giving Prolog nothing but a variable name as a query is the same as asking it to tell you the meaning of the universe. :slight_smile:

8 ?- JABBERWOCKY.
