Stacks and queues

Are there any plans for having things like stacks and queues in the near future?

I needed a stack the other day (for dependency tree iteration), and I ended up creating a ‘’ separated list in a variable. It works perfectly, but the code is very confusing and difficult to change.

Good suggestion, will look into it for a future version.

I just added it to the todo list for the next major version of FB, with a suggestion on how to implement it :)
