In part 4 of this series we add some unit testing,
improve our tokenizer and implement the primitives
In this blog post we will go over some significant changes, from implementing APL's array model to introducing dyadic operators!

÷ 1 2 3 -⍨ 1.1 2.2 3.3 can output
10 5 3.33333333.
Let's build a simple APL interpreter! APL is an array-oriented programming language I picked up recently. The ease with which I can write code related to mathematics, its strange built-ins (which look like
⍣) and the fact that it is executed from right to left make it a fresh learning experience!
