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.
