Having a script like

    #!/usr/bin/perl
    print "hello\n";
[download]

and running it from the command line using

    $ perl script.pl
[download]

will use the perl interpreter perl specified on the command line to run the script, no doubt. Same holds true for

    #!/some/weird/line/containing/perl
    print "hello\n";
[download]

but I was surprised to see that

    #!/usr/local/bin/python
    print "python!"
[download]

when put into script.py and run via

 
    $ perl script.py
[download]

(note the perl on the command line) will call the python interpreter without complaining! Also, a script like

#!Some Weird Comment
print "perl!";
[download]

will throw an error message:

$ perl script.pl
Can't exec Some at t1 line 1.
[download]

So, the deal is that if the shebang line contains the pattern perl somewhere, perl will actually run the script, whereas when it doesn't contain the perl pattern, it will try to run whatever's specified on the shebang line?

Anybody knows more about this?
