One subtlety is that the value of a method call ("message") in a cascade is still the ordinary value of the message, not the receiver. This is a problem when you do want the value of the receiver, for example when building up a complex value. This can be worked around by using the special yourself method that simply returns the receiver: [2]
Cascading can be implemented using method chaining by having the method return the current object itself. Cascading is a key technique in fluent interfaces , and since chaining is widely implemented in object-oriented languages while cascading isn't, this form of "cascading-by-chaining by returning this " is often referred to simply as "chaining".

Cascade classifiers are available in OpenCV, with pre-trained cascades for frontal faces and upper body. Training a new cascade in OpenCV is also possible with either haar_training or train_cascades methods. This can be used for rapid object detection of more specific targets, including non-human objects with Haar-like features. The process ...
While many fast-food joints claim they serve “real” chicken, some still rely on antibiotic-laden, factory-farmed mystery meat. Here are 7 chains that actually use high-quality, real chicken.
The method cascade syntax was adopted from Smalltalk. [76] This syntax provides a shortcut for invoking several methods one after another on the same object. Dart's mixins were influenced by Strongtalk [citation needed] [77] [78] and Ruby. Dart makes use of isolates as a concurrency and security unit when structuring applications. [79]
