I uploaded a small demo of a D repl i've been playing with, might
be of some interest. It's not a robust bit of code, and is not my
idea of a proper repl, but shows some possibilities. The video
shows the repl running as a web server (using vibe) with a
browser client which adds some pretty.

Code is at: https://github.com/callumenator/dabble
Note: the repl is windows only, as it uses Dll's and some custom
loading code. When full dynamic loading support comes along, i
guess it could run under linux, and probably be a bit more stable.
