I never used any of these, so please take this with a grain of salt.

AFAIU, these solutions are too limited at the moment. They suffer from
the same problem as current ":cache" parameter, i.e., they seem unable
to cope with blocks that refer and execute other blocks. 

IMO, for anything serious, we need to implement something that is able
to capture the "closure" of a block. In this case, all blocks belonging
to that closure would be marked as read-only during the process, so as
to avoid race conditions. We also need to be able to retrieve all the
results from all the blocks involved.

Regards,
