What is the preferred way of writing subj. in Lua?
Say, I want to write code that does '#' on value x. I can write:
while #x do break end
do local _ = #x end
(function () return #x end)()
... and so on.
Is there something that has least runtime and size overhead,
i.e. doesn't create extra branches or stack allocations in bytecode?
