Figure out a sane way to do resource release #3
Description
In particular, when I tear down after an error condition in DclStatement.cxx, I need to call close() on the table I've open()ed because that aquired a lock I need to release.
Thing is, the current code doesn't use exceptions at all. And it feels unnatural to pad everything in a try-catch block if there's no finally clause available.
OTOH, I can't use goto as this would require me to move all initializations to the front of the function. C99 was invented over a decade ago. I'm not going back.
