Checking for calling context

[Robin Sheat]

Hey there,
I have a set of functions that send an XML element, wait for a response, 
parse the response, and return it. However, there are often cases where 
the resulting XML is never used, and so parsing it is pointless. Is 
there a way that a sub can tell where the result is going to go, so that 
it can not do the parsing if the result is going to be immediatly 
discarded?

Something like this:
foo(a,b,c);
%result = foo(c,d,e);

sub foo {
        ...do stuff...
        if (-result isn't discarded-) {
                return parseResult($result);
        }
}
