Not a perfect solution but it does solve the problem of not having to use all the put statements and other grammar which as you note is cumbersome to read, let alone write. I agree though, a more elegant solution to this problem would be useful.

If a behavior script is used or properties or objects then I can not read (and potentially revise) the script right in the script that is making the object. I have to open something else if I want to revise the script. Of course I can have a comment that says "look here for the script" and it is generally obvious from "set the script of button "Sample" to <some property and/or object reference>.

Yes there are behavior scripts, but this is about the best practice of placing a script in a script (to set the script of an object) and having it as clear as possible.
