memory leaks - Githubissues

owner attribute in Obj struct doesn't fix the problem. There has to be way to ensure programs below dont result in memory leak

fun idx(arr: [int], i: int) -> int {
    return arr[i]
}

fun main() {
    print(idx([1, 2, 3, ], 1)) # the array allocated on the heap would be lost
}

fun log(s: string) {
    print(s)
}

fun main() {
    log("sahl seems nice") # the string allocated on the heap would be lost
}

`./target/release/sahl samples/sample.sahl -c`

`valgrind --leak-check=full -s ./sahl exe.bin`
