-Avoiding the unusual [[modified assignment]] (using as function the 2-[[train]] <source lang=apl inline>⍎⎕NS</source>) makes for a much more readable version would be:
+Avoiding the unusual [[modified assignment]] (using the 2-[[train]] <source lang=apl inline>⍎⎕NS</source> as modifying function) helps:
+:<source lang=apl inline>
+ns←ns container.(⍎⎕NS) ⍬
+</source>
+Finally, splitting the 2-train apart makes it even clearer:
 :<source lang=apl inline>
 ns←⍎ns container.⎕NS ⍬
 </source>
-This makes it clearer that the name <source lang=apl inline>ns</source> is reassigned to a new [[namespace]] inside the <source lang=apl inline>container</source> namespace, with the new namespace taking the original value of <source lang=apl inline>ns</source> as name.
+A new [[namespace]], with the original value of <source lang=apl inline>ns</source> as name, is created inside <source lang=apl inline>container</source> and the character representation <source lang=apl inline>'#.container.ns'</source> is returned from <source lang=apl inline>⎕NS</source> to <source lang=apl inline>⍎</source> which evaluates the name to a reference, that in turn replaces the previous value of <source lang=apl inline>ns</source>.
