Yes. That wrapper just executes the script as if it were a bookmarklet.

It just produce the Javascript source as a string. For example,
uneval('foo') == '"foo"'

I assumed that the alerts were coming from the web page. If only the
user script is producing the alerts, then you don't need that wrapper,
since you can just define a function in the Greasemonkey sandbox.

If that is the only thing you need, you can skip alert or custom
functions and just use window.focus.
