Any powerful language allows bad coding practices. So style and
consistent idiom use is important.  In this case the rule could be:
"avoid idioms where local constructs require global changes".

Such shortcuts don't need global changes, could define

local function at(s,i) return s:sub(i,i) end

and you would not be typing many more characters, plus your readers
will see the explicit function call and be grateful.
