Metamethod operator

Hi!

I have a feature suggestion for Yuescript:

# metamethod operator

a = close: true, close#: => print "out of scope"
b = add#: (left, right) -> right - left
c = key1: true, #:add, key2: true

d, e = a.close, a#.close
f = a#\close(1)

Compiles to

local a = setmetatable({close = true}, {__close = function(self) return print("out of scope") end})
local b = setmetatable({}, {__add = function(left, right) return right - left})
local c = setmetatable({key1 = true, key2 = true}, {__add = add})

local d, e = a.close,  getmetatable(a).__close
local f =  getmetatable(a).__close(a, 1)

thanks!

No files, tests, or entry points are named. Start by locating the compiler handling metamethods, table construction, and property access, then use the proposed YueScript examples and expected Lua output as the acceptance reference.
