This is a bug report for perl from fawaka@gmail.com,
generated with the help of perlbug 1.40 running under perl 5.20.1.
-----------------------------------------------------------------
Currently, when perl tries to run a script and it encounters a hashbang
line not containing the string "perl" (e.g. /usr/bin/python), it will
instead run that executable. This works for most other languages, but for
perl6 this doesn't switch gracefully for obvious reasons.
The attached patch tries to fix that, so that #!perl6 files will DWIM.
