Unlike Common Lisp, the other main dialect, Scheme follows a minimalist design philosophy specifying a small standard core with powerful tools for language extension.
Scheme is primarily a functional programming language. It shares many characteristics with other members of the Lisp programming language family. Scheme's very simple syntax is based on s-expressions, parenthesized lists in which a prefix operator is followed by its arguments.s in other Lisps, the term  thunk  is used in Scheme to refer to a procedure with no arguments. The term proper tail recursion refers to the property of all Scheme implementations, that they perform tail-call optimization so as to support an indefinite number of active tail calls.
