- " Adapted from Perl indent file by Rafael Garcia-Suarez <rgarciasuarez@free.fr>
-
- " Suggestions and improvements by :
- " Aaron J. Sherman (use syntax for hints)
- " Artem Chuprina (play nice with folding)
- " TODO:
- " This file still relies on stuff from the Perl 5 syntax file, which Perl 6
- " does not use.
- "
- " Things that are not or not properly indented (yet) :
- " - Continued statements
- " print "foo",
- " "bar";
- " print "foo"
- " if bar();
- " - Multiline regular expressions (m//x)
- " (The following probably needs modifying the perl syntax file)
- " - qw() lists
- " - Heredocs with terminators that don't match \I\i*
-
- " Only load this indent file when no other was loaded.
