-### Background
-
- * Chapter 2 defines some basic mathematical notation and
-constructions that are they pervasively throughout this dissertation.
-
- * Chapter 3 presents a literature survey of continuations and
-first-class control. I classify continuations according to their
-operational behaviour and provide an overview of the various
-first-class sequential control operators that appear in the
-literature. The application spectrum of continuations is discussed as
-well as implementation strategies for first-class control.
-
 ### Programming
 
- * Chapter 4 introduces a polymorphic fine-grain call-by-value core
-calculus, λ<sub>b</sub>, which makes key use of Remy-style row polymorphism
-to implement polymorphic variants, structural records, and a
-structural effect system. The calculus distils the essence of the core
-of the Links programming language.
+ * Chapter 2 illustrates effect handler oriented programming by
+   example by implementing a small operating system dubbed Tiny UNIX,
+   which captures some essential traits of Ritchie and Thompson's
+   UNIX. The implementation starts with a basic notion of file i/o,
+   and then, it evolves into a feature-rich operating system with full
+   file i/o, multiple user environments, multi-tasking, and more, by
+   composing ever more effect handlers.
 
- * Chapter 5 presents three extensions of λ<sub>b</sub>,
-which are λ<sub>h</sub> that adds deep handlers, λ<sup>†</sup> that adds shallow
-handlers, and λ<sup>‡</sup> that adds parameterised handlers. The chapter
-also contains a running case study that demonstrates effect handler
-oriented programming in practice by implementing a small operating
-system dubbed Tiny UNIX based on Ritchie and Thompson's original
-UNIX.
+ * Chapter 3 introduces a polymorphic fine-grain call-by-value core
+   calculus, λ<sub>b</sub>, which makes key use of Rémy-style row
+   polymorphism to implement polymorphic variants, structural records,
+   and a structural effect system. The calculus distils the essence of
+   the core of the Links programming language. The chapter also
+   presents three extensions of λ<sub>b</sub>, which are λ<sub>h</sub>
+   that adds deep handlers, λ<sup>†</sup> that adds shallow handlers,
+   and λ<sup>‡</sup> that adds parameterised handlers.
 
 ### Implementation
 
- * Chapter 6 develops a higher-order continuation passing
-style translation for effect handlers through a series of step-wise
-refinements of an initial standard continuation passing style
-translation for λ<sub>b</sub>. Each refinement slightly modifies the notion
-of continuation employed by the translation. The development
-ultimately leads to the key invention of generalised continuation,
-which is used to give a continuation passing style semantics to deep,
-shallow, and parameterised handlers.

+   development ultimately leads to the key invention of generalised

-to abstract machine as we plug generalised continuations into
-Felleisen and Friedman's CEK machine to obtain an adequate abstract
-runtime with simultaneous support for deep, shallow, and parameterised
-handlers.

 ### Expressiveness
- * Chapter 8 shows that deep, shallow, and parameterised notions of
-handlers can simulate one another up to specific notions of
-administrative reduction.
 
- * Chapter 9 studies the fundamental efficiency of effect handlers. In
-this chapter, we show that effect handlers enable an asymptotic
-improvement in runtime complexity for a certain class of
-functions. Specifically, we consider the *generic count* problem using
-a pure PCF-like base language λ<sub>b</sub><sup>→</sup> (a simply typed variation of
-λ<sub>b</sub>) and its extension with effect handlers λ<sub>h</sub><sup>→</sup>.  We
-show that λ<sub>h</sub><sup>→</sup> admits an asymptotically more efficient
-implementation of generic count than any λ<sub>b</sub><sup>→</sup> implementation.
