| yeah - getting rid of such macros is a very good idea in general.

ok, then I continue to work on this. I think I better check assembly code
to remain the same (in general since for example new for(;;) form is
completely different - in old code is inspired by the macroses who
could change 'entry' variable in theory - but now it will not be possible
and not needed so we could use more 'eye-candy' for(;;) form). Thanks
for comments.
