Some more info:

• while exhibits the same problem as C-style for.

  <Reveal this spoiler or all spoilers in this node or all in this thread>

• However, bare blocks are not affected.

  <Reveal this spoiler>

• next exhibits the same problem as redo.

  <Reveal this spoiler>

I also came up with a concise, minimalistic problem definition:

Why do these two loops have different outputs?

{
   print("norm: ");
   local $_ = 'fred';
   for (; /./g ; print("<$&>"),1) {      }
   print("\n");
}
{
   print("next: ");
   local $_ = 'fred';
   for (; /./g ; print("<$&>"),1) { next }
   print("\n");
}

next: <><><><>
