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

It may be worth noting that one difference between the case for C and 
for Scheme is that all the Scheme compilers which currently aim for R5RS 
compliance (and some that don't) also include "interpreters" that are 
capable of executing a source file without requiring a separate compile 
step.  So the degree of applicability of the notion of scripts is far 
greater across all relevant Schemes, than it is for most C implementations.

That said, I agree that the "ignore first line" semantics may not be the 
best possible compromise.
