MHO: this is a really ugly wart on the language, and it does not solve
the problems people would want to solve. It might solve *your* problem
but that's not enough to justify a wart of this size.
We do need to do something about the fact that EXECUTE can't access
plpgsql variables, though I'm afraid that fixing that is going to
require a rather complete overhaul of plpgsql :-(. But it needs one
anyway.
