This is great! That was exactly what I wanted to hear.

The ex module has already done a great work so I think thats a good
starting point. But I'd suggest we have several smalles libs for
different categories. That way you dont need to include process and file
management if you only need to get and set environment.

What do you think about this as a start:

env.getenv(name)
env.setenv(name, value)
env.environ()

fs.attributes -- this is from luafilesystem
fs.chdir(pathname)
fs.mkdir(pathname)
fs.currentdir()
fs.dir(pathname)
fs.dirent(pathname)
fs.lock(file, mode, offset, length) 
fs.unlock(file, offset, length)

proc.pipe()
proc.sleep(seconds)
proc.spawn(...)
proc.wait(proc)

It is basicly the ex module but just different prefixes. I believe that
will help it to scale without being bloaty.

I'd like to add "glob" but I don't know how it can be implemented in windows.
