toy language n.

A language useful for instructional
purposes or as a proof-of-concept for some aspect of
computer-science theory, but inadequate for general-purpose
programming. Bad Things can result when a toy language is
promoted as a general purpose solution for programming (see
bondage-and-discipline language); the classic example is
Pascal. Several moderately well-known formalisms for
conceptual tasks such as programming Turing machines also qualify
as toy languages in a less negative sense. See also MFTL.
