4 | # Each line in that file is a separate test. |
5 | # There are five columns, separated by tabs. |

7 | # Column 1 contains the pattern, optionally enclosed in C<''>. |
8 | # Modifiers can be put after the closing C<'>. |

10 | # Column 2 contains the string to be matched. |
11 | # |
12 | # Column 3 contains the expected result: |
13 | # y expect a match |
14 | # n expect no match |
15 | # c expect an error |
