Is this behavior correct?

Hi all!
I encountered some corner cases where overflow checking for "-"
doesn't work as I would expect:
user=> (- Integer/MAX_VALUE Integer/MIN_VALUE)
-1
user=> (- Long/MAX_VALUE Long/MIN_VALUE)
-1
The problem seems to be that negating MIN_VALUE yields MIN_VALUE
again, so it slips through t
