Monks, Saints and the like,

consider this piece of code: 

my @aha = (1,2,3,4,5);

my $ref = \@aha;

my $ref2="$ref";

print "@$ref\n";
print ref($ref), "  $ref\n";
print ref($ref2),"  $ref2\n";

This shows best the current problem I'm facing. I have an interpolated reference within a scalar. If I retrieve it, the ref operator does not recognize it as reference anymore. My question is: a) After such an interpolation happens - is the object the reference is/was pointing to destroyed if this was the last reference (before interpolation). (Only then b makes sense)

b) how could I raise the interpolated reference from the dead so that it would be recognized as a reference (could do with regexp - brrr) and that I can really use it as such.

Quite franky I expect the answer "Your code is broken". :-)
