createDropTargetFor: session ^ = (
^you if: session source
isMovingMyItem: [you createDropTargetForItemMove]
otherwise: [you createClientSuppliedDropTargetFor: session]
)

Some benifits by introducing a #you preserved word (which means *my sender*):
1 Objects will know who sends a message to it
2 Parts/guests will know the whole/host, the time they are being referred to

For example, in Squeak:
DropEvent>>sentTo: anObject
“Dispatch the receiver into anObject”
self type == #dropEvent ifTrue:[^anObject handleDropMorph: self].

could now be:
DropEvent>>recieved
“formerly known as #sentTo: anObject”
“Dispatch the receiver into anObject”
self type == #dropEvent ifTrue:[^you handleDropMorph": self" "reciever knows sender so this is not needed anymore"].

The only things I think Smalltalk might have gone wrong with syntax are:
# should have been for comments (and #. to end comments)
while
“” should have been for symbol.

Now upside down :(
