Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_sym, *args) ⇒ Object

Implement a trap for a method that might be missing. Any method not listed here will default to the @list Array attribute if @list #respond_to? the method. This nifty feature allows us to “inherit” all methods related Array which will be operated upon the @list Array attribute.

def method_missing(method_sym, *args)
  if @list.respond_to?(method_sym)
    # The array @list responds to this method - use it on @list
    @list.method(method_sym).call(*args)
  else
    # Raise the #method_missing error
    super
  end
