If the last method in the chain returns an interesting value, then that method wouldn't return an error object on failure.

I guess even if you need to return false values, you can still do

    if(  ! eval { $count = $obj->GetCount(); 1 }  ) {
        # Can determine count
    }

so Perl makes it pretty easy to turn exceptions into Booleans. My real-life "more painful" example was in C++ (I don't see many thrown exceptions in Perl).

But every time I start down the road of throwing exceptions in Perl, I run into a lack of standardization and don't manage to pick an exception module to use. So I don't have a good excuse.
