My post "The Environment as a Value" might be of interest to you.
https://groups.google.com/forum/#!searchin/clojure-dev/immutable$20environment/clojure-dev/S8BawG7nzJA/qfCd7hn67aoJ It contains a lot of similar ideas. An important point is that you don't necessarily need an interpreter to get the benefits of an immutable isolated environment: this can still be fully compiled. In terms of state mutations, they key point is that you need some form of dependency graph: if you update one var, this can then trigger a recompilation of dependent vars to get you to a consistent new state. This also solves the problem of circular references as a by-product. It was a cool idea, but nobody seemed very interested at the time :-( On Tuesday, 9 July 2013 00:55:18 UTC+1, kovasb wrote: > > I believe a reify-able clojure interpreter would be useful and interesting. > > For instance, for debugging, partial evaluation, environment capture / > manipulation, and a variety of tasks that currently require resetting the > environment just to see the behavior of code. > > I imagine this being mostly useful at the repl, for exploring the behavior > of programs, and for temporarily changing the meaning of pieces of programs > without digging into source code. > > Anyone with me?
