lib to convert builtin.object to string/int, non efficient

[rd4com]

Will it be possible to convert thoses in mojo in the future ?
https://github.com/rd4com/mojo-object-conversion/

Update: Thanks to Stole from the discord for his discoveries.
my previous attempt is in unusablecode.mojo for great laugh :D

fn main():
    var o=object(-123)
    var o2:Int64 = object_to_int(o)
    var s=object("hello")
    var s2:String = object_to_string(s)
    print(o2)
    print(s2)

edit on 10th september:
It is getting better now with codeV2.mojo

fn main() raises:
    var obj = object("hello")
    if OW.is_string(obj):
        var str:String = OW.string(obj)
        print(str)

    print("int/float-------")
    obj = object(123)
    if OW.is_int(obj):
        OW.mut_int_to_float(obj)
    if OW.is_float(obj):
        print(OW.float64(obj))

    print("list-----------")
    obj = object([])
    if OW.is_list(obj):
        OW.push_to_list(obj,object(123))
        OW.push_to_list(obj,object("hello"))
        print(obj)
