<walterbender> the Python version has this
<ignacio> I think you can save data to boxes?
<walterbender> ignacio, we need a stack (with push and pop) like in the Python version
<walterbender> and then a way to open a file to save to the stack and a way to export the data
<ignacio> walterbender, in "human" lang: a dictionary/dict converted block?
<walterbender> ignacio, a stack is a special kind of list

<walterbender> first on first off, first on last off,
Add push, pop, show stack, empty stack, save stack, load stack
