Does anyone know why you can't use 0x800... in Kotlin?
With the below, I get an error:

fun readTopmostBitFromLong(value: Long): Boolean {
    return value and 0x8000000000000000L != 0L
}

one workaround: 0x8000000000000000UL.toLong()

[ephemient]

in this case you can simply replace the function with value < 0 though
