    PR11590 Revert "PR6954: make ++/-- operation trigger automatic global printing"
    
    This reverts commit 982b88bd950381434a8325e550eff9df59f59dcd.
    
    Pretending that pre/postfix ++/-- operations only writes to its argument
    messes up the optimization of a variable that is assigned and then
    only used through post/prefix ++/--operators.
