For instance this prevents among many other things the ability to construct and evaluate merkle trees and other hashed data structures in tapscript. OP_CAT by adding a general purpose way to concatenate stack values would overcome this limitation and greatly increase the functionality of tapscript. +Bitcoin tapscript lacks a general purpose way of combining objects on the stack restricting the expressiveness and power of tapscript.

OP_CAT aims to expands the toolbox of the tapscript developer with a simple, modular and useful opcode in the spirit of Unix <ref>R. Pike and B.
