" This file still relies on stuff from the Perl 5 syntax file, which Perl 6

" does not use.

" - 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.
