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 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.
