Q
A very {high level language} by Per Bothner based
on {lazy} generalised sequences. Q has {lexical scope}, and
some support for {logic programming}[?] and {constraint}
programming. The language includes small subsets of {Common
Lisp} and {Scheme}.
Q was a test-bed for programming language ideas. Where {APL}
uses {arrays} for looping, Q uses generalised sequences which
may be infinite and may be stored or calculated on demand. It
has {macros}, {primitives} to run programs, and an
{interactive} command language.
Q is implemented in {C::}, and comes with an {interpreter},
{compiler} framework, libraries, and documentation. It runs
on {Linux} and {SUN 4} and should work on any 32-bit {Unix}.
Latest version: 1, as of 1993-06-07. Development stopped in
1994.
