I start all my Raku programs with

Why? If you aren't adding options to 'env', surely this is the same as
using '/usr/bin/bash'.
No, this is a standard shebang (#!) hack to accomodate differering
installation paths. The #! requires a fixed absolute path. So things
which are often installed in different places (such as raku above) like
/usr/local/bin or /opt/something and accessed via the user's $PATH
setting, putting in this line makes the script more portable.
The user's export environment, including the PATH setting, is
automatically included, even if you have no shebang at all:
$ cat test
type python3
echo $PATH
$ chmod+x test
$ ./test
python3 is /usr/bin/python3
/usr/lib64/qt-3.3/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/poc/.local/bin:/home/poc/bin
I don't understand how your reply is related to the previous discussion.
If you don't have a shebang, then the default is to run it with the shell.
