 The following rules apply to modifiers:
 \begin{itemize}
 \item
-  The \lstinline!each!\indexinline{each} keyword on a modifier requires that it is applied in an array declaration/modification, and the modifier is applied individually to each element of the enclosing array (with regard to the position of \lstinline!each!).
+  The \lstinline!each!\indexinline{each} keyword on a modifier requires that it is applied inside an array declaration or modification of an array, and the modifier is applied individually to each element of the enclosing array (with regard to the position of \lstinline!each!).
   In case of nested modifiers this implies it is applied individually to each element of each element of the enclosing array; see example.
   If the modified element is a vector and the modifier does not contain the \lstinline!each! prefix, the modification is split such that the first element in the vector is applied to the first element of the vector of elements, the second to the second element, until the last element of the vector is applied to the last element of the array; it is an error if these sizes do not match.
   Matrices and general arrays of elements are treated by viewing those as vectors of vectors etc.
