Ah, I figured out at least part of what was happening. I have a web app,
with Ring and Jetty and Compojure, and I have a form where people can
upload images. The Ring has middleware that lets the uploaded images appear
as a map with a pointer to a File:
{:size 3874, :tempfile #<File
/var/folders/kr/pgx6tzks6kg48hgdnj1f7dt80000gn/T/ring-multipart-6398198897870847417.tmp>,
:content-type "image/png", :filename "sponsored_by_pink.png"}{:size 0,
:tempfile #<File
/var/folders/kr/pgx6tzks6kg48hgdnj1f7dt80000gn/T/ring-multipart-1255729774892979983.tmp>,
:content-type "application/octet-stream", :filename ""}
The map is then stored in a var called "interactions". I had another page
where I took everything in "interactions" and gave it to cli-yaml and
dumped that to the screen. Up till now I've been dealing with plain text
that gets input via HTML forms, and there were no problems. But now, when I
upload a file, and cli-yaml tries to serialize that, it runs into some
understandable problems.
