3 | # This is a home for regular expression tests that don't fit into | |
67a2b8c6 | 4 | # the format supported by re/regexp.t. If you want to add a test |
ff3f963a KW |
5 | # that does fit that format, add it to re/re_tests, not here. Tests for \N |
6 | # should be added here because they are treated as single quoted strings | |
7 | # there, which means they avoid the lexer which otherwise would look at them. | |
