"exists() just doesn't shortcut" :)
It is about lvalue context too, see exists documentation:
"This surprising autovivification in what does not at first--or even
second--glance appear to be an lvalue context may be fixed in a future
release." (5.8.x)
There is no pragma to shut it off.
I think it is possible to create a source filter to make exists() do
what you want.
