toy language
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.
