I'm not sure if it covers your question but perl supports a coderef syntax for method calls (which BTW is much faster)

$thing->$c_get_object->$c_get_another_object->$c_do_something

(ATM I can't find the corresponding perldoc) ¹

So when your sure that the methods are not dynamically added or deleted at run-time from the corresponding class, you can make sure that that those methods exist and init the coderefs like constants (e.g. in a BEGIN block).

UPDATE: 1) greping helps, see perltooc#Inheritance Concerns:

Because the &UNIVERSAL::can method returns a reference to the function directly, you can use this directly for a significant performance improvement: 
           for my $parent (@ISA) {
               if (my $coderef = $self->can($parent . "::CData1")) {
                   $self->$coderef($newvalue);
               }
           }
