I added the following comment to CLJ-927 as a possible solution.
It would be convenient if I could handle unknown tags using some sort of
catch-all key in data-readers (say 'default). The associated function should
take two arguments: the tag and the literal value. If there is no 'default key
in data-readers, then an error would be thrown (same as Clojure 1.4).
I think it's a simple way to allow the programmer to take control without
having to add new API or data types. It's just one distinguished key ('default,
:default something like that) and one additional line of doc.
I have a patch that I'm planning to submit if dev people indicate support for
it. The alternative of binding another dynamic var as the unknown tag handler
would also work for me.
