Synopsis
each %hash
Returns a two-element list consisting of the key and
value for the next element of a hash. With successive calls to
each, you can iterate over the
entire hash. Entries are returned in an indeterminate order. When
the hash is entirely read, a null list is returned. The next call
to each after that will start a
new iteration. The iterator can be reset either by reading all the
elements from the hash or by calling the keys function in scalar context. You
must not add elements to the hash while iterating over it,
although you are permitted to use delete. In a scalar context, each returns only the key.
There is a single iterator for each hash, shared by all
each, keys, and values function calls in the program.
This means that after a keys or
values call, the next each call will start again from the
beginning.
