         <p>"Uiua's array model went through a lot of iterations during development. At first, it used a flat, vector-based model ala K and Q. Then, I switched to BQN's Based array model. That was really complicated to implement primitives for, so I tried something else."</p>
         <p>"I switched to a flat array model with \"fill elements\". While arrays could not be nested, operations which would create nested arrays in other languages would instead create jagged arrays with special fill elements at the end of some rows. While this worked, the code was scattered everywhere with checks for fill elements, because they had to propagate through everything. It also had the unfortunate effect of making byte arrays take up 2 bytes of space, since a bit had to be used to indicate whether the byte was a fill element or not. Also, a lot of operations, such as "<Prim prim=Transpose/>", don't really make a lot of sense with jagged arrays."</p>
-        <p>"Finally, I switched to the current model, which resembles J's Boxed array model. While you can do something resembling J's "<code>"box <"</code>" using "<Prim prim=Box/>" (and "<code>"open >"</code>" with "<Prim prim=Unbox/>"), I designed functions like "<Prim prim=Partition/>" and "<Prim prim=Group/>" to allow selecting uniformly-shaped rows from a non-uniform list in an effort to minimize interaction with jagged data."</p>
