Hi Greg,

thank you for your answer!

I was not aware of this, and this is actually described in the REDIRECTIONS
paragraph of the manual page.

Nevertheless, when evaluating the second snippet

       failwith()
       {
         1>&2 {
           printf 'Failure: '
           printf "$@"
           printf '\n'
         }
         exit 1
       }

bash does not report the syntax error and resumes interpretation, so that
as far as I understand, there is something to investigate here.


Best regards,
Michael
