Well, it's written in Haskell, even more intimidating than Scheme :-)

Its author, however, is very responsive, and I can imagine that he can
add support for features you probably need $(Q#|(B or help you in writing a
JSON filter as described in the documentation.

For example, I've done this to make a Markdown document insert SVG
images if converted to HTML and PDF `images' if converted to LaTeX.
