I'd suggest comp.unix.programmer, or maybe comp.unix.shell or
comp.lang.perl.

The exact behavior varies among OSes, but yes, it will usually fail in
one way or another.  E.g., Linux behaves the way you describe, while
Solaris passes just the first argument (perl) to the interpreter
(/usr/bin/env) and ignores the rest of the line.

I don't think it can be done with env, but I've heard this works:
#!/bin/sh
#! -*-perl-*-
eval 'exec perl -xTw "$0" ${1+"$@"}'
  if 1==0;
