prolog code造句

Atoms are usually bare words in Prolog code, written with no special syntax.
Functional programming languages that use single assignment include Clojure ( for data structures, not vars ), Scala ( for vals ), SISAL, Standard ML . Non-backtracking Prolog code can be considered " explicit " single-assignment, explicit in a sense that its ( named ) variables can be in explicitly unassigned state, or be set exactly once.
