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

| "     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*
