Fortunately, the state of affairs is not quite as bad.
For Hagimeno's example
set myArray to {myVar, "starts with", "john"}
one could use
set myAction to "return (\"" & item 1 of myArray & "\" " & item 2 of myArray & " \"" & item 3 of myArray & "\")"
run script myAction
to get the desired result.
It is a bit awkward, and I don't know about the performance, but it will work.
Beware to keep track of the presence and absence of quotes: the resulting script has to look like
return ("john is great" starts with "john")
All the best and Happy New Year to all of you!
Thomas
