Is `i + (f(),i+i)' well defined? Or to focus in, is `i + (f(),1)' well
defined? i.e. is the sequence point before and after the evaluation of i=1 by
calling f _between_ the evaluation of the i in i + and the modification? I
thought this issue was not resolved last time it was discussed here. 

Is this any different from i = (f(),1)?
