An S-expression (S stands for symbolic) is a convention for representing data structures in a text form.[...]
S-expressions were originally intended only as machine representations of human-readable M-expressions, but Lisp programmers soon started using S-expressions as the default notation.[...]
Program code can be written in S-expressions, using prefix notation.[1]
