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

|
14 " TODO:
|
|
|
15 " This file still relies on stuff from the Perl 5 syntax file, which Perl 6
|
|
|
16 " does not use.

|

19 " - Continued statements

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