Playing around a bit now I recognized
whats so irritating within me.

It is, that I primarily want to do a for loop
(an iterator, you can say 'each' too),
but this is not the main construct here.
Instead this is the catch, and the loop, which
is the active part of the problem definition
(no: solution definition) is plunged inside it.
(don't know if I could express what I mean =%-P ).

And meditating over the big picture of
this code snipped I realized now, how
similar it looks to BASIC-like goto constructs:

  for x to y step z 
  do
     ...
     if abc 
     then
        goto :out
     endif
  endfor
  print "after"
out:

:-)
