Well, I don't know what Ada does with PRAGMA exactly, but look at
these examples from Oracle:
http://psoug.org/definition/pragma.htm
You wouldn't *execute* those at runtime, but at least for some of
them, the runtime behavior would depend on whether or not they were
specified. It certainly seems possible that we might want to have
similar things.
My proposal doesn't block it.
The pragma in Ada has three levels - function, block, statement. I propose (in this moment) just statement level syntax, but I am sure, so other levels are possible.
I would to have a autonomous functions or autonomous blocks too, and Ada syntax (same with PL/SQL) is good.

Pavel
