+    Foam::is_contiguous
 
 Description
-    Template function to specify if the data of a type are contiguous.
+    A template class to specify that a data type can be considered as being
+    contiguous in memory.
 
-    The default function specifies that data are not contiguous.
-    This is specialised for the types (eg, primitives) with contiguous data.
+    Normally only integral and floating-point types can be considered
+    contiguous, but some other types (eg, FixedList, Pair, Vector etc)
+    consisting purely of these fundamental types can be considered
+    as having a contiguous memory layout as well.
+
+Note
+    In OpenFOAM 1906 and earlier, the contiguous trait was handled
+    by templated \c contiguous global functions.
+
+    While possible to mark this as deleted, this does not detect or
+    prevent specializations. Thus omit the usual housekeeping.
