Because you don't know if lua is in /bin, /usr/bin, /usr/local/bin,
/home/username/work/totally-not-porn/im-serious/bin/, etc. but env is
usually in /usr/bin and as long as $PATH is right, it doesn't matter
where lua is.

I'm not saying that env *must* be in /usr/bin, but I think it's more
probable for env to be there than lua.

OK, but what's the purpose of 'env'? Can you not write #!lua?

Interesting, I thought I'd seen that done before. I wonder why that doesn't work?
