9 " Adapted from Perl indent file by Rafael Garcia-Suarez <rgarciasuarez@free.fr>
10
11 " Suggestions and improvements by :
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.
17 "
18 " Things that are not or not properly indented (yet) :
19 " - Continued statements
20 " print "foo",
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*
28
29 " Only load this indent file when no other was loaded.
