Enchilada

Concatenative language invented by Robbert van Dalen. Its computational model is based on a purely functional Term Rewriting engine as opposed to the more conventional stack based model.

The ultimate research goal of Enchilada is: 'Information cannot be destroyed'. This is as far reaching in that even (unwritten) Terms are immutable in Enchilada.

To make this feasible, Enchilada is built on Persistent Data Structures, in particular Weight Balanced Binary Trees.
