Not sure what else you would choose to use it for if you could choose lexical scoping instead.

Dunno. I like dynamic scoping. It has some interesting uses. How would do the same as below without it? (Im not saying it cant be done, just that it would be harder) 

our $Debug=0;

# lots of subs that work

sub doesnt_work_quite_right {
  local $Debug=1;
  
  # code that we are trying to debug
  
}

In order to do the same thing we would have to do that as 
my $Debug;

sub doesnt_work_quite_right {
  my $olddebug=$Debug;
  $Debug=1;
  
  # code that we are trying to debug
  
  $Debug=$olddebug;  
}

Which is both a PITA and far too reminiscent of debugging VBA for my taste.
