In that respect I think '=' would be pretty good too.
And possibly '!'.

However,

    if (long-expression
        | more-expresson):
        |decorator-function(blah blah)
        def foo(): pass

Could do the same with != and '==', but at least that's different from
'!' and '='.  One could write

    if bar(long_variable_name
           =value):
        =decorator-function(blah blah)
        def foo(): pass

though that seems a bit contrived.
