Interesting idea. :-)

AFAIK, it is currently not possible.
Recently, experimental JSON support has been added [1].

Well, I am not sure that Guile can combine several languages. Other
said, Guile can compile and run Scheme scripts and it can too compile
and run say ECMAscript but I do not know if one could write/define a
module using Scheme and call this very module from ECMAscript; as for
example Python and Hy [2] (lisp) do using the Python AST module.

And combining is not easy because some "concepts" in one language does
not necessary apply to another language.
It is not because the compiler has several front-ends (for different
languages) and use the same internals [3] that it can mix them; e.g.,
GCC: Fortran, C, Ada, etc. and it is not straightforward to combing
them.
Otherwise, life would be too simple. ;-)


But I should miss a point...

As a starting point, I would ask to Guile's mailing list how to write
a module in say Scheme and use it from say ECMAscript --- or least
where start from to do so.


All the best,
