+TO-DOs:
 
-LONGER-TERM STUFF:
+These are features that have been requested, and have been considered,
+but are not yet implemented, because I'm undecided about how or whether they
+should be implemented, and/or because they are difficult and/or time-consuming
+to implement.
 
-- Add a += operator, so that additional elements can be appended to a list or
-  array
+Also, some of these features tend to push libconfig toward becoming a
+general-purpose structured-data storage mechanism, which is really not the
+intended purpose of this library. I think something like sqlite is better
+suited for that sort of thing.
 
-- Add support for #include's; a patch was submitted for this previously, but it
-  is not reentrant (uses static global variables), so can't be used as-is. I
-  just haven't gotten around to implementing this because it's not a trivial
-  change, and free time being in limited supply as it is...
 
-- Add limited support for preserving comments?
+* Add an option for safe type conversions; that is, report an error
+  rather than silently truncating out-of-range values to 0 (namely int64 ->
+  int).
 
-- Add support for unicode strings? A bit problematic, since flex doesn't
-  support unicode input, AFAICT. But maybe a way to convert between
-  parsed UTF-8 strings and std::wstring.
+
+* Add support for copying settings from one configuration to another. Need a
+  recursive function to copy a setting and call itself on all child settings.
+
+
+* Add a += operator, so that additional elements can be appended to a list or
+  array. The issue with this is defining a consistent syntax. For example:
+
+  x = ( 1, 2, 3 );
+  x += ( 4, 5 );
+
+  Should this result in ( 1, 2, 3, 4, 5 ), or ( 1, 2, 3, ( 4, 5 ))? I believe
+  it should be the latter. However, only the former makes sense for arrays.
+
+
+* Add the ability to insert/delete elements at any position in a list or
+  array. A simple implementation would be expensive (shift all the elements
+  by one for every insert/delete), and a more efficient implementation would
+  add a lot of complexity to the library.
+
+
+* Add limited support for preserving comments?
+
+
+* Add support for unicode strings? A bit problematic, since flex doesn't
+  support unicode input, AFAICT. But maybe supply convenience functions to
+  convert between parsed UTF-8 strings and std::wstring.
