- /(a)b|/
+ /-- This set of tests is not Perl-compatible. It checks on special features
+     of PCRE's API, error diagnostics, and the compiled code of some patterns.
+     It also checks the non-Perl syntax the PCRE supports (Python, .NET,
+     Oniguruma). Finally, there are some tests where PCRE and Perl differ,
+     either because PCRE can't be compatible, or there is potential Perl
+     bug. --/
+ /-- Originally, the Perl 5.10 things were in here too, but now I have separated
+     many (most?) of them out into test 11. However, there may still be some
+     that were overlooked. --/
