In addition to the answers above it is possible to pass
arrays and hashes by reference without using
a \. The way to do this is to define a function
with a prototype as explained in perlsub.
For a more complete explanation I can recommend FMTYEWTK About Prototypes, which says in detail what they are, where they are buggy, and the various design flaws that make them something to avoid on the whole.
