If you put a hash reference into an array

you do not store any actual hash data in the array.
So if you change the hash, then later pull the hash reference from the
array and access it, you get changed data.
push @array, { %hash };
This creates an anonymous hash and populates it with the contents of %hash. It
makes a copy of %hash. Of course, if %hash has any references, they will be
copied but not their contents.
