Would a good solution to this be for try/catch to _automatically_

Interfaces are more java-y, which has pluses and minuses. Here for
example, I think the compiler itself, which is written in java, needs
to be able to seq things (ie, your source-code forms). *Maybe* you

Nope, the core interfaces were written before Protocols existed. Making them
protocols is a bootstrapping problem, although ClojureScript shows that it
may be possible to fix this.
If you want to make a Java class seqable, you'll have to wrap it in another
type that you create.

Would now be a bad time to observe there was a large change made to the way
exceptions are handled, and the lack of guard-rails (no tests for exception
handling behavior) may have contributed to this regression?

Fair enough. :) Complete test coverage is intractable.
But in clojure, there are only a handful of tests that contain a catch and none

I suppose you could iterate over all known Vars and construct a map from fns
to the Vars that contain them. Then, given a fn, you can look up the Var and

I remember not really understanding the way defn hung metadata off of its
functions. In 1.2, it returned different responses on successive calls to
defn. for example:
user (clojure-version)
1.2.1
user (defn my-func a docstring! [x] x)
#'user/my-func
user (meta #'my-func) ;; var first
{:ns
It's not a regression. It is a known breaking change.
The change merely owned up the the fact that we cannot in fact communicate all
actual errors through Java code, due to checked exceptions. This is an enduring
problem with Java, and you are going to see it rear its ugly head in Java
itself
I don't know what the right solution is either, but here is a JIRA ticket
