As shmem pointed out, refaddr is 5.8.8 core (Scalar::Util)

Otherwise, you could do that by hand, like: 
my @array = (1,2,3,4);
my $ref = \@array;

my $addr = hex +($ref=~/(?<=\()[^)]+/g)[0];

Which should not *that* slow, especially if you
do big business with GRT.

To get the complete ref string back, do a simple: 
my $rs = sprintf "ARRAY(0x%x)", $addr;

My question: why can't you take the whole
"ref" string, including "Array(...)"?
