s, and he is a prominent author in the field.

With David Wise, Friedman wrote a highly influential paper on lazy programming
Lazy evaluation
In programming language theory, lazy evaluation or call-by-need is an evaluation strategy which delays the evaluation of an expression until the value of this is actually required and which also avoids repeated evaluations...

, specifically on lazy streams (ICALP 1976). The paper, entitled "Cons should not evaluate its arguments," is one of the first publications pushing for the exploration of a programming style with potentially infinite data structures and a form of programming that employs no computational effects (though programs may diverge). Over the 1970s, Friedman and Wise explored the topic in depth and also considered extensions to the world of parallel computing.

In the 1980s, Friedman turned to the study of Scheme. He explored the use of macros for defining programming languages; with Kohlbecker, Felleisen

, and Duba, he co-introduced the notion of 'hygienic macros' in a 1986 LFP paper that is still widely cited today. With Haynes and Wand, he simultaneously studied the nature of continuation objects, their uses, and the possibilities of constraining them. Following that, Friedman and Felleisen

, a text book on programming languages. As such, it changed the landscape of language text books in the 1980s, shifting the focus from surveys of languages to the study of principles via series of interpreters. Today's text books on this topic tend to follow this organization, though use operational semantics and type theory instead of interpreters. Like The Little LISPer, Essentials of Programming Languages is a long-living book and is in its third edition now.

Most recently, Friedman resumed work on his "Little" series with The Reasoned Schemer (with Byrd and Kiselyov), explaining logic programming via an extension of Scheme.
