\o/ toclose! (I'll echo that a more Luaish syntax would be preferred
but I trust the Author's judgement on this.)
I thought I'd also share that another useful local qualifier would be
<static>. This would be a variable scoped as normal but is initialized
once when the surrounding closure is created. i.e.:
function foo(...)
local <static> cache = {}
end
is syntactic sugar for:
do
local cache = {}
function foo(...)
end
end
