Program composition for Unix pipes.
$ todo 'Add USAGE/examples here'
The idea of a "higher-order program (HOP)" is inspired by the idea of higher-order functions from functional programming. A HOP provides programs that take other programs as arguments, and applies them to lines of stdin.
Of course, the idea is not novel. timeout and xargs are HOPs. Shells also
provide higher-order functions like eval and exec (among others). test is
often both a program and a shell builtin. Pipes themselves fill a similar
role to map and filter from the FP paradigm, too.
