    \$\begingroup\$ Can't you use 1 (or 2, 3, etc.) instead of () so that you return value 1? It would save 1 byte. Also is this answer REPL only? Maybe if you load code with load you can not include () or anything at the end, because it will not be accessible anyway? \$\endgroup\$ Commented Nov 29, 2017 at 23:20

    \$\begingroup\$ @PrzemysławP You are right on both points, I tried with eval and this works as you said. Thanks a lot! \$\endgroup\$ Commented Nov 30, 2017 at 8:42
