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

13 | # Column 2 contains the string to be matched. |

15 | # Column 3 contains the expected result: |
16 | # y expect a match |
17 | # n expect no match |
18 | # c expect an error |

20 | # Columns 4 and 5 are used only if column 3 contains C<y> or C<c>. |
