UUID Comparison fails on script start (Possible Duplicate)

UUID Comparison is... Possibly cause by the same as this bug

function test()
    if ll.GetOwner() == ll.GetOwner() then
        ll.Say(0,"EQUAL")
    else
        ll.Say(0,"NOT EQUAL")
    end
end
test()
touch_start = test

Prints

NOT EQUAL

On script start, but then

EQUAL

on touch

More comprehensive script

function test()
    ll.Say(0,"============================")
    local own1 = ll.GetOwner()
    local own2 = ll.GetOwner()
    
    local comp = own1 == own2
    
    if comp then
        ll.Say(0, `UUID EQUAL: {comp}`)
    else
        ll.Say(0, `UUID NOT EQUAL: {comp}`)
    end
    if own1 == own2 then
        ll.Say(0, `UUID EQUAL`)
    else
        ll.Say(0, `UUID NOT EQUAL`)
    end
    
    ll.Say(0, tostring(own1))
    ll.Say(0, tostring(own2))
    
    own1 = tostring(own1)
    own2 = tostring(own2)
    
    comp = own1 == own2
    
    if comp then
        ll.Say(0, `STRING EQUAL: {comp}`)
    else
        ll.Say(0, `STRING NOT EQUAL: {comp}`)
    end
    
    if own1 == own2 then
        ll.Say(0, `STRING EQUAL`)
    else
        ll.Say(0, `STRING NOT EQUAL`)
    end
    ll.Say(0, own1)
    ll.Say(0, own2)
    ll.Say(0,"============================")
end
test()
touch_start = test

Fixed in the latest release, along with the similar string comparison issue. Thanks for the example scripts and easy test case.

UUIDs in Luau are userdata
, which is the reason this fails.
See: https://www.lua.org/manual/5.1/manual.html#2.5.2
> Objects (tables, userdata, threads, and functions) are compared by reference: two objects are considered equal only if they are the same object.
However I think
 this could be fixed by implementing the equality operator in C.

Try the script
They compare just fine, after script start
