A: Showcase your language one vote at a time

Cy Factoid Cy is a postfix language that operates on a stack. The order in which operands are expected on the stack is based not on what makes sense, but the order in which it would be most convenient to pass on arguments in a point-free style.

Say you have a checksum that comes out to higher = 256, lower = 1. Binary conversion would turn that into ['10000000', '1'].
