I have no idea what, if anything, Clojure the language(s) *should* do
about this issue, but I can explain the reasoning behind CLJX.
CLJX uses the reader to statically analyze toplevel forms in a file
and generate new ones according to declarative rewrite rules.
The motivating use case was to make

There's a format-like function in the Closure library.

and call it like

One thing that I found helpful was to define log as a macro so that
it'll be inlined in the JavaScript.
That way Chrome will give you the correct line numbers (for the

Using JavaScript from ClojureScript is very straightforward.
There are a few points where interop is awkward, but that wasn't the main
reason I wrote a new library (in Clojure).
There were two primary motivations for that.

Manoj,
I wrote a ClojureScript wrapper around the D3 JavaScript library,
https://github.com/lynaghk/cljs-d3
and took some liberties with the D3 API to make it more concise and
otherwise Clojure-like.
For instance, you set attributes in D3 like

.attr("x", 5)
.att
