The closest may be
local t = {}
setmetatable(t, {__newindex = function(t,k,v)
local i = k:match'^_(%d+)$'
rawset(t, i and tonumber(i) or k, v)
end})
function t._1() print '1' end
t[1]()

var there can lead to some confusion:
function f(x)[1](y) end
because parenthesis are used in multiple ways in Lua (as well as in
math): expression grouping, function calls, and function argument
lists.
