"For convenient iteration via `for in`, ..."? about shelljs

[arturadib]

Yeah I debated over this, ended up going with the hash because for (file in ls()) was closer to Bash's for loop and less verbose than .forEach(function(file){ ... }), but I agree that arrays are more powerful.

Let's gather some thoughts from other folks.

@tkazec actually, if you're still up for it, I'd love to see a pull request that changes the result of ls() and find() to array. this might take a bit of work to make all tests pass though (via ./scripts/run-tests.js), since the tests make use of hash results (like 'filename' in ls()).

I'll dig a bit deeper once we have a pull request.

thanks!

Awesome! I was going to do it last night but ended up being unavailable. Looks good!
