Now think about the alternatives if your goal is to have the table ready to go at runtime without any computational overhead at all, e.g. a CRC table.
And if we can restrict :immediate using some security principal in the future so it can only do things that are not destructive -- and always yield the same result -- in other words, do not depend on the environment, then this use would be totally fine.
Your example is well within the realm of pure evaluation, and does not make use of unbounded (environment-dependent) evaluation. But I think this ticket can be morphed into "once the security sandboxing is here, prevent :immediate to do something silly".
Would you agree with that? I can create another ticket for .loadlib. Thanks, Audrey
