I am the inventor of multiple ends on the same line. This way, in a
language where all of several nested constructs end with an end - not
going to name the language but it's Julia - instead of
end
end
end
end
end,
one combines the uninformative lines into one by writing
end end end end end,
and with four-space indentation the ends align neatly with the starts.
Technically, the ends on the remaining line of ends are backwards.
