 DESCRIPTION
-    This is analogous to the C operator sizeof.  It attempts to assess

     Similar sharing of memory occurs with literal strings.
 
+    For associative arrays, only the value part of the name/value pair
+    is counted.

     The minimum value for sizeof(x) occurs for the null and error values.
