If you squint, it's the very beginnings of a REPL ;)

I'm also able to dynamically eval some code with import now, but the result is a module...

$ ./node_cli.js repl
:yo
=> (+ 1 2 3)
[Module: null prototype] {  }
=> (prn 1)
1
[Module: null prototype] {  }

kinda worked around it:

$ ./node_cli.js repl
:yo
=> (take 3 (range))
[0,1,2]

Could be fun to try this locally. Branch: repl
