Well, I can use 'scheme-r5rs', but then another scheme implementation,
not scheme48, will be called.

Can't I explicit specify scheme48 in there?

Something like: #!/usr/bin/env scheme48

So how would I load a specific structure?

I see that structures' definitions can use (open foo) to specify
dependencies, but I also see that I can't use (open foo) in the REPL.

No problems in this particular scenario. Everything works great but I'm
wondering if there is a simple way to create small scripts other than
building images.
