1 /-- This set of tests is not Perl-compatible. It checks on special features 2 of PCRE's API, error diagnostics, and the compiled code of some patterns. 3 It also checks the non-Perl syntax the PCRE supports (Python, .NET, 4 Oniguruma). Finally, there are some tests where PCRE and Perl differ, 5 either because PCRE can't be compatible, or there is a possible Perl 6 bug. --/ 7 8 /-- Originally, the Perl >= 5.10 things were in here too, but now I have 9 separated many (most?) of them out into test 11.
