• Lobster language - https://aardappel.github.io/lobster/memory_management.html
• two pointers are vital because they have a start pointer (beginning of the memory block) and end pointer (end of the block). When an allocation is done, the start pointer is moved forward, when memory is released, the start pointer is shifted backwards
