You can recompile in the repl, as it's just a shell command away:

#;> ,s csc -s test.scm -o test2.so
#;> ,l test2

There is a small caveat, though: dlopen'd shared libraries are not automatically
unloaded, so you will add more and more code to the system (since Scheme
gets compiled to C, and C code is not garbage collected). This isn't a serious
problem, but should be kept in mind for long running sessions.
On some systems, undloading is actually supported, but somewhat
experimental.
