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?
