Not really useful in this case, but should give the idea:

   getItem of {"a", "b", "c"} at 2
   --> "b"

Okay... You've put an "of" there. But if I read it correctly, "of" and "in" should be optional. It's written as
[ of | in ]
and not
( of | in )
like it is done with the
( on | to )
which is not optional for defining a handler



What I wanted to create is a handler: on the_last weekdayname for a_date

so that I can write
 the_last Monday for current date


Aha, you were thinking at that one...

IIRC, it never worked to write user-defined handlers with a direct parameter but without that "of" or "in" preposition (unless in very, very early versions of AS?).
I guess it would have led to too many ambiguities.


But AppleScript's syntax allows such constructs for non user-defined commands, so that the ASLG still mentions the fact (not very clearly, I agree).

HTH,
