I took a look at the Clara's code. This is excerpt from the comment of
"defsession" defmacro: "..Each source is eval'ed at compile time, in
Clojure (not ClojureScript.)..".
So, this is a solution, but not clear ClojureScript solution :(

Thank you Alan for very helpful information. I know about Clara but don't
watch its progress attentively fore some time :(

Ru,
Take a look at the approach used by Clara
(https://github.com/rbrush/clara-rules.) It works in both Clojure and
ClojureScript. It translates the DSL using eval at macro-expansion time to
generate the productions - see defsession.
Will take a look at rete4frames again when I get a chance.
Many thanks for the explanations. I will be experimenting to deside where
to go further.

If you need eval then you need to be OK with pulling in a lot of code and
giving up Closure advanced optimizations and dead code elimination.
Whatever small size savings an interpreter might offer, it would still
suffer from this fundamental problem.

That I understand. Only one more question. Can I unload ClojureScript
Compiler after I done with "eval"? This scenario is suitable very well to
my task.

ru,
eval is there in clojurescript. It's just in a separate namespace. This is
a good thing, because it leads to big space savings in the regular case.

First thing that comes to my mind is MAXIMA Computer Algebra Program from
LISP ecosystem. That is a system for the manipulation of symbolic and

While eval is an important part of Clojure, it's also very rarely used.
I've been working with Clojure for almost eight years now, and I've written
60 Clojure libraries. Despite that, I've used eval less than half a dozen
times.
Having a way of evaluating ClojureScript in ClojureScript is a nice

All we know that JIT is a Just In Time compiler and that JIT is an
important part of Java compiler nowerdays. Maybe JIT ideas can be applied
to ClojureScript "eval problem" solution?

LISP implementations often have a compiler and an interpreter
simulteniously. As I know LISP interpreter is a very simple program and
often used as an example in classes. Maybe ClojureScript should include
such interpreter for such important task as evaluation of dinamically
generated code?

Clojurescript does have eval, in the cljs.js namespace:
https://crossclj.info/ns/org.clojure/clojurescript/1.7.228/cljs.js.cljs.html#_eval
Take a look at http://yogthos.net/posts/2015-11-12-ClojureScript-Eval.html for
an example and https://swannodette.github.io/2015/07/29/clojurescript-17/ for

ClojureScript has cljs.js/eval, which while not as convenient as
clojure.core/eval, can accomplish the same effect.
The reason why ClojureScript doesn't have a standard eval is because it
adds a huge amount of overhead for relatively little gain. You need to load
the entire ClojureScript compiler
Dear ClojureScript users and team!
Without "eval" function ClojureScript can't be recognized as a full-fledged
LISP. "Code as data" paradigm can't be implemented without "eval". What
purpose of code constructed programmatically, if it can not be evaluated?!
