Right, but I'm looking for the Spark frontend of this hide clause.

Of course. I can pass any private type, but how do I initialize such a thing?

This call has to occur in normal Spark.
argv_array has which type? array (Positive range <>) of System.Address?
And the examinder says:
*** Semantic Error : 54: Illegal attribute: Address.

How do I do this in a Spark frontend? Of course, I can hide the whole
program, but this is not really a solution.
