This is a loop exit: 

sub f { last; }

say "before loop";

{
   say "start of loop";
   f();
   say "end of loop";
}

say "after loop";

({ ... } is technically a loop. You can also use while/until loop, a foreach loop, or a C-style for loop.)

This outputs 

before loop
start of loop
Exiting subroutine via last at -e line 1.
after loop

So the documentation you quoted refers to programs such as the following: 
$SIG{ __DIE__ } = sub { last; };

say "before loop";

{
   say "start of loop";
   die "!";
   say "end of loop";
}

say "after loop";

However, the code doesn't do what the documentation claims it does. 

before loop
start of loop
Can't "last" outside a loop block at -e line 1.

choroba pointed out that the documentation was corrected a short while ago.

However, the documentation is wrong, and it was corrected a short while ago. (Thanks to choroba for identifying this.)
