1) the fact that the default shell (cmd.exe) or the explorer (in case
of doubleclick) ignores the shebang line doesn't mean all programs
do. It may be used by some Unixie shell he uses or by the
Windows version of Apache.
2) Perl itself does care about that line. And exits if it finds
something that doesn't match /perl/i. Try to run this script with
Perl.exe:
#!/bin/sh
print "Hello world\n";
3) Perl processes that line and uses whatever options you
specified on the line. This means that
c:\> perl
#!perl -w
print "x=$x\n";
^Z
and
c:\> perl -w
print "x=$x\n";
^Z
wil give you the same warnings.
This means that if you start your script with
#!perl -w
it will be run with warnings turned on even if the user doesn't ask for
it ;-)

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
