Binary Operators

An expression x op y is evaluated as follows:

• if x is a primitive and y is an object with op, y[op](x, y)
• if x is an object with op and y is a primitive, x[op](x, y)
• if y has op and is a subclass of x, y[op](x,y)
• if x has op and is a subclass of y, x[op](x,y)
• if x has op, x[op](x,y)
• if y has op, y[op](x,y)
• else builtin(x,y)
