ccn told you what it does. But actually what it does is

print %hash; # prints hash as a list of its keys and values.

- as in -

print @{ [ %hash ] } # prints hash as a list of its keys and values.

[ ... ]    # an array reference is created... and
@{ ... } # that array reference is de-referenced... it is no more.
