+Allow for the metaproperties: C<XID Start>, C<XID Continue>,
+C<NF*_NO>, C<NF*_MAYBE> (require the DerivedCoreProperties and
+DerviceNormalizationProperties files).
+
+There are also enumerated properties: C<Decomposition Type>,
+C<Numeric Type>, C<East Asian Width>, C<Line Break>. These
+properties have multiple values: for uniqueness the property
+value should be appended. For example, C<\p{IsAlphabetic}>
+wouldbe the binary property, while C<\p{AlphabeticLineBreak}>
+would mean the enumerated property.

Case Mappings? http://www.unicode.org/unicode/reports/tr21/
-lc(), uc(), lcfirst(), and ucfirst() work only for simple cases, where
-the mapping goes from a single Unicode character to another single
-Unicode character. See lib/unicore/SpecCase.txt (and CaseFold.txt).

=head2 Support for rerunning debugger
There should be a way of restarting the debugger on demand.

+=head2 Create debugging macros
+
+Debugging macros (like printsv, dump) can make debugging perl inside a
+C debugger much easier. A good set for gdb comes with mod_perl.
+Something similar should be distributed with perl.
+
+The proper way to do this is to use and extend Devel::DebugInit.
+Devel::DebugInit also needs to be extended to support threads.

+See p5p archives for late May/early June 2001 for a recent discussion
+on this topic.
