  This Warning is signalled by methods which are deprecated.
  
  The use of Object>>#deprecatedExplanation: aString and Object>>#deprecated: aBlock explanation: aString is recommended.
  
  Idiom: Imagine I want to deprecate the message #foo.
  
  foo
  	^ 'foo'
  
  I can replace it with:
  
  foo
  	self deprecatedExplanation: 'The method #foo was not good. Use Bar>>newFoo instead.'
  	^ 'foo'
  
  Or, for certain cases such as when #foo implements a primitive, #foo can be renamed to #fooDeprecated.
  
  fooDeprecated
  	^ <primitive>
  
  foo
  	^ self deprecated: [self fooDeprecated] explanation: 'The method #foo was not good. Use Bar>>newFoo instead.'
