To make it clear: I'm thinking about adding new operators '+++' and
'---', which would return values. Existing '++' and '--' would remain
the same - they do not return value for purpose:
if you have code like

foo ();
++i;
bar ();
..

it is better to keep it like this and still do not get the warning
about ignored value (returned by ++i)

On the other hand, having ++ behave as expected by many would be very
nice - maybe we should have a special case for ++ and -- so that they
will return void in general, but if expected some value, they will
return it...
