       Module Stack
	: sig end

       Last-in first-out stacks.

       This module implements stacks (LIFOs), with in-place modification.

       type 'a t

       The type of stacks containing elements of type 'a .

       exception Empty

       Raised when Stack.pop or Stack.top is applied to an empty stack.

       val create : unit -> 'a t

       Return a new stack, initially empty.

       val push : 'a -> 'a t -> unit

       push x s adds the element x at the top of stack s .

       val pop : 'a t -> 'a

       pop s removes and returns the topmost element in stack s , or raises Empty if the stack is empty.

       val top : 'a t -> 'a

       top s returns the topmost element in stack s , or raises Empty if the stack is empty.

       val clear : 'a t -> unit

       Discard all elements from a stack.

       val copy : 'a t -> 'a t

       Return a copy of the given stack.

       val is_empty : 'a t -> bool

       Return true if the given stack is empty, false otherwise.

       val length : 'a t -> int

       Return the number of elements in a stack.

       val iter : ('a -> unit) -> 'a t -> unit

       iter  f	s applies f in turn to all elements of s , from the element at the top of the stack to the element at the bottom of the stack. The
       stack itself is unchanged.

NAME

       stack - Create and manipulate stack objects

SYNOPSIS

       package require Tcl 8.2

       package require struct ?1.2.1?

       stackName option ?arg arg ...?

       stackName clear

       stackName destroy

       stackName peek ?count?

       stackName pop ?count?

       stackName push item ?item ...?

       stackName size

DESCRIPTION

       The  ::struct::stack command creates a new stack object with an associated global Tcl command whose name is stackName.  This command may be
       used to invoke various operations on the stack.	It has the following general form:

       stackName option ?arg arg ...?
	      Option and the args determine the exact behavior of the command.	The following commands are possible for stack objects:

       stackName clear
	      Remove all items from the stack.

       stackName destroy
	      Destroy the stack, including its storage space and associated command.

       stackName peek ?count?
	      Return the top count items of the stack, without removing them from the stack.  If count is not specified, it  defaults  to  1.	If
	      count  is  1,  the  result is a simple string; otherwise, it is a list.  If specified, count must be greater than or equal to 1.	If
	      there are no items on the stack, this command will return count empty strings.

       stackName pop ?count?
	      Return the top count items of the stack, and remove them from the stack.	If count is not specified, it defaults to 1.  If count	is
	      1, the result is a simple string; otherwise, it is a list.  If specified, count must be greater than or equal to 1.  If there are no
	      items on the stack, this command will return count empty strings.

       stackName push item ?item ...?
	      Push the item or items specified onto the stack.	If more than one item is given, they will be pushed in the order they are listed.

       stackName size
	      Return the number of items on the stack.
