Well, there is a REPL, but it's not that great:
$ nim i
>>> for i in 0..10:
... echo "Hello World"[0..i]
...
H
He
Hel
Hell
Hello
Hello
Hello W
Hello Wo
Hello Wor
Hello Worl
Hello World
Edit: It's even buggier than I remembered, best avoid it and use "nim -r c file" instead.
What bugs or things-that-are-not-great have you run into with Nim's REPL?

It seems that you can't use any libraries. After using import it doesn't work anymore.
The closest thing to what you're asking about is Pixie [1], which is a Clojure-like language implemented in Pypy's RPython.

It'd be possible to implement a Clojure in Nim, you'd just have to port the datastructures and enough primitives to bootstrap the language core (see core.clj, Clojurescript's core.clj, Pixie's stdlib.pxi).
Could someone give a brief comparison between Clojure and Nim? Let's suppose that we implement Clojure in Nim is this a crazy idea?, What about implementing Shen in Nim?. Many people complain because sbcl is not easy to use with C++ libraries, could an implementation in Nim amilliorate those problems?. Many more questions arise but those mentioned are enough.
