That's how I think too!

We could also make global methods.

With the shortcuts:

   start "/foo/bar"
   stop  "/foo/bar"

What do you think,

   if cpu > 90% then exec method1, method2, method3

makes sense, too?  Our language could handle it.

Sound much more logic.  And the language is much more consistent.

We have to keep the "old" start/stop language as a shortcut!  But the
language implementation is peanuts, the intelligence part in the
background is more work.

We should keep present alert features, too.
