Actually, methods are kinda like infix operators anyway.  One argument is
followed by the method name, which is followed by any other argument(s):

    irb(main):001:0> 4.div 2
    =3D> 2

The div method fits between the operands, when viewed as an operator.  In
fact, that's how other infix operators work:

    irb(main):002:0> 4./ 2
    =3D> 2

I don't know of any way to eliminate the requirement for the dot used
with methods you define, the way built-in operators do, though.
