No. Thats called eval STRING. :-) This would simple parse the output and validate that it is eval STRING is safe. DD output is highly regular with none of the edge cases that make parsing perl hard. Thus it should be fairly straight forward to write code that validates that an arbitrary piece of code conforms to the constraints of a DD output.
