Because Limbo was designed for the Inferno environment, several of these examples consist of simplified versions of already simple Inferno applications in a prototype Inferno implementation. Some appreciation for the resources available in this environment should become evident, but its full description is available elsewhere; the discussion here will focus on language features. However, several of the programs use facilities from the module Sys, which provides an interface to a file system and its methods resembling those of Unix or Plan 9, as well as other useful library facilities.

Some of the programs are annotated with line numbers; they are there only for descriptive purposes.
