Scheme `load` is a procedure; that is, it is executed at run time.
Spock is an offline compiler, so there is no way to load Scheme code
(as opposed to JavaScript code) into a running Spock program.  As far
as I know, Spock doesn't implement `include` either, which would be a
compile-time action.

All I can suggest is that you compile them separately and then concatenate
the resulting JavaScript files.  However, if the SRFIs include macros,
those macros won't be available to your code.

Apparently you are just supposed to supply multiple files of Scheme
code on the Spock command line.

The 'load' not working makes sense now; thanks for the reminder!  It
seems odd that 'include' or something similar isn't available.

Thanks for the suggestion. I think I'll try to cobble soemthing together
using the procedural interface to spock (instead of just relying on the
command-line compile-spock, as I have been doing so far).  The 'spock'
procedure includes an 'import' option, but so far I haven't figured out
how to use it for the above purposes.  I'll have to dig a bit deeper
there.
