That's rather a silly interpretation of what I said, I think.  After all::

	% cat > test.gargle
	#!/usr/bin/env gargle
	
	asdfasflsafhklsfhklsdfhsdf
	max at oxygen:~/tmp% file test.gargle
	test.gargle: a gargle script text executable

`file` knows how /usr/bin/env is used because it's not only a standard 
Unix idiom, it's the primary purpose for which it exists.  That's not 
the case with endless variants of /bin/sh scripts whose first statements 
involve running another interpreter in some clever way that's not 
detected by _that_ interpreter's processing, which is what the 
previously discussed tricks amount to.
