Arrays are delimited by spaces in RIB, but some people have been known to use commas, perhaps out of habit. Pixie passes through the extra commas and prints them on stdout. In comparison, Aqsis and BMRT both throw syntax errors and refuse to display the cube. While Pixie's behavior is more fault-tolerant, it's certainly a bit confusing at first.
