call: foo( $obj->{dbh} );
First of all, the dbh is already a reference. There is
no point in creating another one.
Secondly, when you pass variables as arguments to a
perl function, it actually operates on the variable.
If you modify the variable, the variable is modified
in the callers context. You may want to assign the
dbh to a local (lexical) variable to avoid modifying
the original.
