    set a boolean value to a default value if it is not set (nil)

    a question for you please :)
    Is it possible to set a boolean value to a default value if it is not set (nil)?

    I am trying the ternary lua way but it does not work for me :/ https://wiki.gideros.rocks/index.php/Examples#TERNARY_OPERATOR_https:.2F.2Fwww.lua.org.2Fpil.2F3.3.html
    -- tests
local thover = false -- test
local hover = thover and false or true -- I want to set boolean default = true
print("TEST", hover) -- it always prints TRUE :-/
    I can achieve what I want using this but it is a hack :D
    local thover = nil -- test
local hover2 = thover or 0
if hover2 == 0 then hover2 = false else hover2 = true end
print("TEST", hover2)
    How do you handle this please?

      This should work to assume 'nil' should be seen as 'true'
      hover=thover or (thover==nil)
