Definitely not what you want - compile-time expansion (e.g.

Thanks, has. I was about to reply to Philippe when I noticed you'd beaten me
to it[1]. I suppose you could demonstrate another manifestation of the
potential problem by trying to compile the cited example (app) as a

-------------------
set app to "Finder"
-------------------
--> Syntax Error: Can't set application to "Finder". Access not allowed.
