when it occurs as the first two characters on the first line of a text
file. In this case, the program
loaderhttp://en.wikipedia.org/wiki/Loader_%28computing%29in
Unix-like http://en.wikipedia.org/wiki/Unix-like operating systems parses
the rest of the first line as an interpreter
directivehttp://en.wikipedia.org/wiki/Interpreter_directiveand
invokes the program specified after the character sequence with any
command line options specified as parameters. The name of the file being
executed is passed as the final argument.
As you can see this is not something an interpreter is supposed to do, the
responsability is delegated to the OS's program loader. You could emulate
this under Windows, but I suppose you would be using cygwin or something
similar.

Perhaps not unexpected, but not necessary either. I may be wrong, but it seems reasonable to assume there's a common code base for the Haskell Platform for Linux and Windows versions. Presumably there's code for the parser to the skip shebang line on Linux - there's no reason why it couldn't do the same on Windows. As it is, it's just an unhelpful impediment to having cross-platform scripts (unless there's a good reason for it - I couldn't think of one).
Coincidentally, I am working on functionality which brings shebang line processing to Windows, primarily for Python scripts but it also works with other scripting languages (like Perl). That's not why I posted this, though - I was just given a set of scripts and want to use them on Windows without changing them just for this.
