I'm looking for any programming language, DSL, library or pattern for live scripting but minimizing the expressions reevaluation.

Topological sorting provides non-revaluation of expressions.

Memoization provides a simple way of not re-evaluating but is a waste of memory.

A form of topological ordering can be achieved by maintaining (in each language object) a version number for each dependency but it does not seem to be easily composable/scriptable.

Which available tools would be the most suitable?

Thank you!
