What made me believe that "#!/usr/bin/env perl -w" should work was
the following part of the documentation for env:

   NAME
          env - run a program in a modified environment

   SYNOPSIS
          env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]

It clearly says that the command (COMMAND) takes arguments (ARG).
Indeed it does on the command line, but not on the shebang line.

I'm not sure what to do, if anything, since this behaviour seems
to be so common.  For all I know, someone might count on it.
