It's not a shell, but perl does this:

$ cat 1.sh
#!/bin/sh
echo "Hello world"

$ perl 1.sh
Hello world

$ sed -i '1c#!/usr/bin/perl' 1.sh
$ cat 1.sh
#!/usr/bin/perl
echo "Hello world"

$ perl 1.sh
String found where operator expected at 1.sh line 2, near "echo "Hello world""
(Do you need to predeclare echo?)
syntax error at 1.sh line 2, near "echo "Hello world""
Execution of 1.sh aborted due to compilation errors.

...not that that has anything to do with the original topic...
