It's funny because 'my' will warn, but 'local' is fine:

  perl -we 'use strict;our $f = 10; {my $f = 20; my $f = 30; print $f,"\n"}
print $f,"\n"';
  perl -we 'use strict;our $f = 10; {local $f = 20; local $f = 30; print
$f,"\n"} print $f,"\n"';

The fact that 'local' doesn't warn makes it seem inconsistent to me. But it
could be just the way how I think 'local' works ;p
