> Wrt to repl: the torch7 repl is quite serviceable, so it's worth giving it a try

Sounds great, but:

    $ luarocks install trepl
    Error: No results matching query were found.

Also the torch7 repo[1] mentions:

> Torch is not in active developement

Is there a maintained torch7 repl somewhere?
