A questionably-manufactured metal chess set

It started when Joyce was going to buy a chess set from Amazon. There's nothing wrong with the chess sets there, but they're made of plastic and aren't very interesting. So I offered to make one out of metal instead. Here's what I ended up with:

# This example was run in IRB 1.9.2 p290.
# Initialize x, y, z, and t to some values using a parallel assignment:
> x, y, z, t = 1, 2, 3, 4
=> [1, 2, 3, 4]
# In the case above, '=' has lower precedence than ',', so there's a 4-ary
# lvalue and a 4-element rvalue.
> x, y = z, t = 1, 2
