in thread What operator should perl5porters use for safe dereferencing?

I doubt there exists a situation where I would want to ignore all exceptions.

There do exist situations in which I will want to catch and log any exception and move on to the next task though, but this is a different thing. There's a huge difference between being able to shorten

my $age = do {
 my $boss = $company->boss();
 my $wife = $boss ? $boss->wife() : undef;
 $wife ? $wife->age() : undef
};

to just

my $age = $company~>boss()~>wife()~>age();

and just ignoring anything that might happen while getting that info. Because, you know, if the company has no boss or the boss has no wife, then the age is actually undefined. On the other hand if there was a problem loading the data from the database or where ever, I want to know, because then the value is not undefined. It could not be "computed".

Dare I suggest a Null wife?
