Bingo!!! I use this approach for data science tasks today. Create very specific DSL that has mathematics, set theory, etc. as a context and setup your data science exploration using the dsl as input. Been fairly decent so far. It works for two specific reasons 1. I have a fairly specific dsl that is expressive enough for the task at hand available easily (math notations have been around for centuries now and algorithms for at least 1/2 a century). 2. I use Apache spark - so everything around parallelizing and synchronizing I don’t handle in the code myself (not most of the time).
