There is not much more. The context was about changing  for(;;) to  for(@array) or to  map {} @array and doing it with an editor macro to the worst work of a weak group of perlers. In a training presentation to that group.

My points were:

• This, in its presentation, would trivialize the issues.
• The  for(;;) and  for(LIST) constructs are very different.
• This a rather small issue, surely there are more important problems in the above situation.

Your comparison of the  for(;;) and  while loops is a different issue. For the simple cases I prefer a  for( $i=1; $i < 10_000_000; $i++) as all the loop's controls are there upfront. This assumes good practice, i.e. you don't fiddle with  $i while looping. If you mess with  $i then you should use a  while loop.

You say:

Usually when someone uses a C-Style for loop they are not exploiting the equivalence to a while , but rather using a slightly less readable, more error prone and less efficient form of a for (LIST) loop.

Which is exactly the difference I was refering to with: more cumbersome but more adaptable.

If brevity caused my unclarity, please let me know.
