I found your code in Moses very readable and well structured but I
noticed you use '_' for some 'root' level variables (for lack of a
better term). My understanding (I think I read it somewhere)  was '_'
was supposed to be used in cases where you weren't going to use the
value like in:

for k, _ in pairs(tbl) do
--do something with key and not the value
end

Can I ask where you got that syntax from? I ask out of curiosity (and
potential adoption) as it does seem to make your code very
understandable. Any other comments on '_' as a variable name?
