False or not to false?

    public class TestLuaGlobal : LuaGlobal
    {
        public TestLuaGlobal(Lua lua) : base(lua) { }
        [LuaMember("NeoLuaTestBool")]
        private bool NeoLuaTestBool()
        {
            return false;
        }
    }
with this Lua script
opB = NeoLuaTestBool()
print('opB =',opB)
if opB == false then
   print('OK opB=false')
end
if opB == False then
   print('OK opB=False')
end
Produces the following output
opB = False
OK opB=false

Why display boolean is it different with a capital letter?

opB = NeoLuaTestBool() -- Returns a boolean and stores it in a member from type object
print('opB =',opB) -- Prints the value with the Convert.ToString function of the .net framework. They convert false to "False".
if opB == false then -- compares the object with the constant false --> (bool)opB == false result is true
   print('OK opB=false')
end
if opB == False then -- compare the object with an empty member --> Object.Equals(opB, False) result is false, because the objects are different
   print('OK opB=False')
end

if not opB then -- is a better style, not (bool)opB --> true

if not false then --> not false --> true

if not False then --> not (bool)False --> False is null/nil so it is false --> true
Did I make it clear?
