#call {|Object| ... } ⇒ Object

Creates a new instance and calls its ‘call` method with the given arguments. This method implements the callable pattern, allowing the class to be used like a function while maintaining object-oriented principles.

With configuration block

MyCallable.call(input) do |instance|
  instance.configure(option: value)
end

Parameters:

  • args (Array) —

    Arguments to be passed to the instance’s call method

Yields:

  • (Object) —

    Optional block that yields the new instance before calling

Yield Parameters:

  • instance (Object) —
