Ruby operator method calls vs. normal method calls

Question

I\'m wondering why calls to operator methods don\'t require a dot? Or rather, why can\'t normal methods be called without a dot?

Example

class Foo
  def +(obje         


        

Answer 1

Because Ruby has "syntax sugar" that allows for a variety of convenient syntax for preset situations. For example:

class Foo
  def bar=( o ); end
end

# This is actually calling the bar= method with a parameter, not assigning a value
Foo.new.bar = 42

Here's a list of the operator expressions that may be implemented as methods in Ruby.
