Looking at the BNF specs for TLA+ v1 and v2, the set of infix operators has some changes:
The addition of the <= and \notin operators
The removal of the ? operator
I was also reminded of this when searching through files for the other thread and came across this line in the SANY code. So out of curiosity, what occasioned the removal?
