I can't define "defines" to somebody
confused about definitions.
that would be a feat, indeed. i took "predicate" to refer to only the
relation, w/o the set. if OP had used the term "poset" directly, and
not used "predicate" in the context of the less-function argument to
`sort', i would not have been (as) confused.
Knuth calls this a topological sort.
I'm not sure if anybody else does.
check out the tsort (GNU textutils) info page.
