References to hash elements?

[Arthur Bergman]

Hi,

I am wondering how the references to hash elements are planned to be 
done? The call to set_ must somehow be delayed until the time is right.

$foo = \$hash{key};

$$foo = "bar";

$has{key} is now "bar"

I don't see how the current vtable setup will allow for this in a tied 
situation, or will a tied hash just return a hashelement pmc type that 
will do the call later on?

On another note, is there going to be a PMC flag for tainted data?
