I spoke too soon. using local still soes not present accidental clobbering: 

my $f = "boot";
{local *tmp =\$f; $tmp = "loop"; GG::cc () ;print "$f\n...\n"};

sub cc { $tmp="cc did it"}; 
print "$f\n...\n";

sub cc, happens to use the same dummy variable name $tmp. as a result as the local expression $f gets clobbered. What I want is something that makes $tmp scoped like a my variable.

THe problem I am trying to solve here is simply to always have to write de-reference code when I pass in a reference. I want an alais in the form of a localy scoped variable to the object being dereferenced. It looks like you might be able to do this with a tie or with Data::alias but those are both very heavyweight solutions.
