[r6rs-discuss] [Formal] "#! /usr/bin/env" is not "portable." It's Unix-specific.

Not necessarily.  The draft does not require scripts to be whole files.
As a result, while the Unix script starts on the first line, we are entitled 
to regard the Scheme script as starting on the next line of the same file.  The 
first line of the Unix script is the #!, while the first line of the Scheme 
script is whatever comes next.  In this view, R6RS has to specify the Scheme 
script, but can avoid specifying the first line of the Unix file, which
is then not part of the Scheme script.
