  • list comprehension — (functional programming)   An expression in a functional language denoting the results of some operation on (selected) elements of one or more lists. An example in Haskell: This returns all pairs of numbers (x,y) where x and y are elements of the list 1, 2, ..., 10, y <= x and their sum is less than 10. A list comprehension is simply "syntactic sugar" for a combination of applications of the functions, concat, map and filter. For instance the above example could be written: The term "list comprehension" appears in the references below. The earliest reference to the notation is in Rod Burstall and John Darlington's description of their language, NPL. David Turner subsequently adopted this notation in his languages SASL, KRC and Miranda, where he has called them "ZF expressions", set abstractions and list abstractions (in his 1985 FPCA paper [Miranda: A Non-Strict Functional Language with Polymorphic Types]).
