SWISH::Prog::Queue - simple in-memory FIFO queue class

 use SWISH::Prog::Queue;
 my $queue = SWISH::Prog::Queue->new;

 $queue->put( 'foo' );
 $queue->size;          # returns number of items in queue (1)
 $queue->peek;          # returns 'foo' (next value for get())
 $queue->get;           # returns 'foo' and removes it from queue

SWISH::Prog::Queue is basically a Perl array, but it defines an API that can be implemented using any kind of storage and logic you want. One example would be a database that tracks items to be evaluated, or a flat file list.

See SWISH::Prog::Class.

Overrides base method.

Add item to the queue. Default is to push() it to end of queue.

Returns the next item. Default is to shift() it from the front of the queue.

Returns the next item value, but leaves it on the stack.

Returns the number of items currently in the queue.
