+Arrays are limited in size by the MAXMAPENTRIES variable -- see the
+.B SAFETY AND SECURITY
+section for details. Optionally, global arrays may be declared with a
+maximum size in brackets, overriding MAXMAPENTRIES for that array only.
+Note that this doesn't indicate the type of keys for the array, just the
