Multi-language scripts

[Stephen Scheck]

I'm trying to invoke `guile -s script` where script contains something like
this:

    ,language ecmascript
    display("Hello JavaScript!\n");
    ,language scheme
    (display "Hello Guile!\n")

However, REPL meta-commands do not seem to be available when passing a
script file to Guile with the -s switch.

Does anybody know if there's any way to make it work?
