This bot has the same purpose as run.dlang.io - a sandbox to try 
some things and share code with people. Even though sharing can 
be done with simple 'highlight your message with code and bot's 
reply -> share these messages' I am thinking about ways to make 
it simpler and faster.

Regarding vulnerabilities, if there are any I and 
authors/maintainers of dlang-tour will be interested in fixing 
them ASAP. After all, dlangbot uses tour's code under the hood.

Executable downloading would require me to rewrite the back-end. 
I am not sure if it'll worth it because it's not clear how safe 
that would be for a user and how usable that feature will be. I 
mean, if user already has x86-64 Linux machine (that's what 
dlangbot uses) then will it be any simpler and faster to message 
the bot with code, download an executable and run it than 
compiling it using installed compiler?
