I think the major obstacle is likely to be the difference in idioms.
Any substantial idiomatic piece of Clojure is going to be almost
impossible to automatically translate to _idiomatic_ code in another
high-level language that uses different idioms. You'd also probably
have to introduce a number of "coding conventions" to constrain your
Clojure code in order to avoid "holes" in the translation.
Some questions:
* How do you translate Clojure functions in namespaces spread across
multiple files into a Java class?
* Would it even be idiomatic Java to always have classes full of only
static methods?
* What about Clojure's vast library of functions (esp. higher-order)?
* What would something like
(map (juxt :id identity) (filter (comp not nil? :data)
some-lazy-data-stream))
look like in Blub, if Blub doesn't have keywords, composition,
higher-order functions, lazy data structures?
* How would code that uses STM translate to a Blub without it?
* How idiomatic would Blub code be when Clojure uses immutable data by default?
I think it's a fascinating problem to try to solve for any given
target Blub but I'm not sure how practical it would be, i.e., how
readable the generated Blub code would be to an "average" Blub
programmer...?
