Hi Mike... I see you beat me to posting this :-)

I assert that this should be considered a bug in strict, considering both the documentation that the behavior is undefined, and that B::Deparse says:

% perl -MO=Deparse -Mstrict -le 'my $rv = 42 for (1); print $rv'      
+                                                        
BEGIN { $/ = "\n"; $\ = "\n"; }
use strict 'refs';
foreach $_ (1) {
    my $rv = 42;
}
print $rv;
-e syntax OK

but

% perl -MO=Deparse -Mstrict -le 'foreach (1) { my $rv = 42 } ; print $
+rv' 
Global symbol "$rv" requires explicit package name at -e line 1.
-e had compilation errors.
BEGIN { $/ = "\n"; $\ = "\n"; }
use strict 'refs';
foreach $_ (1) {
    my $rv = 42;
}
print ${'rv'};
