The BLOCK form however does incur a bit more overhead since it has to do all the steps incurred entering and exiting a block. If it's done once, you're probably not going to notice it; if it's a statement you're executing each line for your 1G data file it may add up. Granted it's relatively small and may have been optimized in recent versions, but be aware of the overhead if you're looking for somewhere to shave a few microseconds off after you benchmark (of course always benchmark :).
