Hi

As I understand it, use overload '""'=> \&my_quote; will overload both "" and print.

That is, with both:

$x = "$blessed_obj";
and
print $blessed_obj;

the my_quote subroutine will be called, and the return value assigned to $x (in the first instance) and printed to stdout (in the second instance).

Normally there's no problem in having the same sub serve both "" and print as they both usually require the same processing. However, I have a situation where it would be handy if different subs could be called for "" and print - ie they require *differing* processing.

Is there some way of overloading print and "" with different (separate) subs ?
If not - is there some way that my_quote would be able to determine whether it has been called via the overloading of print or via the overloading of "" ?

My feeling is that the answer to both those questions is "no" ... but I've found in the past (on more than one occasion) that "feeling" is not always a reliable indicator wrt perl.

Cheers,
Rob
