* A ''broken'' round parenthesis creates a [[vector]], where every diamond/line break-separated statement forms an [[element]] in the resulting vector.
* A ''broken'' round parenthesis creates a [[namespace]] if every diamond/line break-separated statement is a ''name-value pair''.
* A ''broken'' round parenthesis creates a [[vector]], if every diamond/line break-separated statement is a value expression. In that case, every such statement forms an [[element]] in the resulting vector.
* A ''broken'' square bracket creates a an [[array]], where every diamond/line break-separated statement forms a [[major cell]] in the resulting array.
* A ''broken'' square bracket creates a an [[array]], where every diamond/line break-separated statement forms a [[major cell]] in the resulting array.
* <source lang=apl inline>()</source> is equivalent to <source lang=apl inline>(⎕NS 0⍴⊂'')</source>
* <source lang=apl inline>()</source> is equivalent to <source lang=apl inline>(⎕NS 0⍴⊂'')</source>
* A ''name-value pair'' consist of a valid APL identifer, followed by a <source lang=apl inline>:</source> and a value expression.
