Only for the loop -- warnings, along with most other pragmas (strict,
feature, etc) are lexically scoped, so you can expect the same behavior
there.
Simple test:
use warnings;
my $x = 1 + undef; # This will warn
{
no warnings;
my $y = 1 + undef; # This will not warn
}
my $z = 1 + undef; # This will warn
