/// This trait is intended to differentiate between joinable and non-joinable objects.
/// Joinable objects are those that interpreter should wait on. F.e. if at least one of
/// arguments of a call instructions is joinable, the interpreter won't execute such
/// call and won't write any state for it in data. This is needed to handle collecting
/// variable from different peers in parallel.
///
/// At the moment, this trait's applied only to errors.
pub(crate) trait Joinable {
/// Return true, if supplied object is joinable.
