This is really interesting, I've been wanting to learn more about Torch for a while but have been reluctant to commit to learning Lua.

Lua is a pleasure to learn and use. The language core is so simple and elegant, you can learn it in a day. Standard library is also very light, which is both strength and weakness.

I use it more and more for hobby projects. Combine it with LuaJIT (which torch uses) and you have the fastest interpreted language around. Give it a try.

I want to reiterate this. I started learning it for guilt because it was created in the university I studied. Then I realised it was really a pleasure to use it. I still use it in many hobby projects nowadays whenever I can.
