That's OK because you don't want to do an operation within
a regular expression, you want to do an operation within
the REPLACEMENT part of the s/// operator (which is (by default)
a string, not a regex).

Read the entry for s/// in perlop.pod, until you get to this part:
e Evaluate the right side as an expression.

I can reproduce your problem with DOS-edited file.
The character at the end of the string confuse the
interpreter.

World writable? Why? Change that to the 'standard'

Typos? Should better be:
-rwxr-xr-x

No, you most likely can't. The error message in your case is very cryptic=
:
josef@bounty:~> ./test.pl
: bad interpreter: No such file or directory
josef@bounty:~> perl test.pl
Hello, world
The CR ath the end of the shebang line will cause the error message to=20
get scrambled. You can see it, if you run the program using script:
^[]2;josef@bounty:~^G^[]1;bounty^Gjosef@bounty:~> ./test.pl^M
bash: ./test.pl: /usr/bin/perl^M: bad interpreter: No such file or=20

What about "perl hworld.pl"?

There is something wrong here. There is no such set of permissions as
"-rwxr-wr-w". They *should* be "-rwxr-xr-x". If that's what they really
are and you just wrote them down wrong when posting here I can't explain
your problem.
If they are actually "-rwxrw-rw-" the perhaps you aren't running the
script as root. (I know the part of your message that I clipped shows that
you *are* running as root, but if you got those permissions wrong perhaps
you got that wrong as well.)
