Unless you choose to be dirty and "trick"[1] Perl into doing it anyway:
print "@{[ $child->Tag() ]}\n";
Thanks to array dereferencing (i.e., @{} ) an anonymous array
reference (i.e., [] ).
Of course, it's more difficult to read and write (i.e., error-prone),
and probably somewhat wasteful considering the extra steps needed to
make it happen, so Jim Gibson's suggestion to print the result
directly or store it into a scalar first is certainly preferred in
good code. :P As I said, it's dirty. ^^
