Try ` instead of '. eval evaluates the expression with a different ns.
Since y is not properly quoted it is not found. ` will resolve y to
its qualified name and everything will work out.

True, it's that Clojure does not have first-class environments, either
dynamic or lexical.

I'd say both Python and Clojure are somewhere in between the classical
extremes of "interp

Or, more simply, Python is an interpreter, Clojure is a compiler. So
Clojure's "eval" actually compiles t
Hi,
I am not familiar with the Python code.interact() thing and what it
does so I may be missing something but if you are looking to do
debugging is there a reason you can't use a Java debugger to debug
your Clojure code? (I have heard some people have had success for
JSwat.) I guess that is not

I don't think so. Python and Clojure are quite different languages.
Python is much more dynamic, with variable lookup happening at
runtime. In Clojure, onl

You need to unquote the x to get its value from the let. You can do
that with the tilde character inside syntax quotes:
user=> (let [x 1] (eval `(inc ~x)))
