I then define `a:append` and `a:prepend` to combine arrays.
~~~
:a:prepend (aa-a)
here #0 , [ dup fetch [ &, a:for-each ] dip
swap dup fetch [ &, a:for-each ] dip + ] dip
&store sip ;
{{
:copy dup fetch [ &, a:for-each ] dip ;
---reveal---
:a:prepend (aa-a)
here #0 , [ copy swap copy + ] dip &store sip ;
:a:append (aa-a)
swap a:prepend ;
:a:append (aa-a)
swap a:prepend ;
}}
~~~
