Pornography is a term traditionally used by APLers to describe code that is hard to read, or uses unusual constructs. Code golf often results in pornographic code.

Examples

In APL – an Interactive Approach, the authors the authors describe the following code as “almost pornographic”:

r←(+/x×y)÷((+/(x←x-(+/x)÷⍴x)*2)×+/(y←y-(+/y)÷⍴y)*2)×.5

The APL2 Idiom list includes the following entry:

X'line1',0Y'line2' ⍝ Pornography. Combining two lines into one.

Morten Kromberg asked one of his colleagues to “Please avoid this kind of pornography:”

ns(container.⎕NS)

A much more readable version would be:

nsns container.⎕NS
