Awesome catch! The current implementation of Range.pick() is based on Range.roll(), which uses nqp::rand_I() to choose a random value from an integer range. I'm guessing nqp::rand_I() is returning a 32-bit number, and so Range.pick/ Range.roll are actually only returning values from 2**80 to 2**80+2**32-1 . Pm
