| 10 " Aaron J. Sherman (use syntax for hints) | |
| 11 " Artem Chuprina (play nice with folding) | |

| 29193 | 13 " TODO things that are not or not properly indented (yet) : |
| 14 " - Continued statements | |
| 15 " print "foo", | |

| 17 " print "foo" | |
| 18 " if bar(); | |
| 19 " - Multiline regular expressions (m//x) | |
| 20 " (The following probably needs modifying the perl syntax file) | |
| 21 " - qw() lists | |
| 22 " - Heredocs with terminators that don't match \I\i* | |
