T is a dialect of Lisp derived from Scheme [#!rrs!#]. It is comparable in power and expressivness to other recent Lisp dialects such as Lisp Machine Lisp [#!Weinreb81!#], Common Lisp [#!CLtL!#], and NIL [#!White79!#], but fundamentally more similar in spirit to Scheme than these other Lisp dialects.
T is an attempt to create a powerful and expressive language which is portable, efficient, and suitable for a broad variety of applications, including symbolic, numerical, and systems programming.
T draws from many sources in its attempt to provide a complete yet simple and unified system. For the most part, the language's designers are collators, not originators. Common Lisp, NIL, and Scheme have been the strongest influences.
