Suggestion to add default argument values in case 'nil'

Bulletin Board
#1

Currently Lua doesn’t have an easy way to add default argument values in case you want to give your function parameters default values when they don’t exist.

What I want:

local function foo(a = 1, b = "something")
    print(a, b) -- 1 something
end

foo(a, b)

What we currently must do:

local function foo(a, b)
    a = a or 1
    b = b or "something"
    print(a, b) -- 1 something
end

foo(a, b)
