From my (admittedly limited) experience with Scala, yes, you can freely use

I'm facing a little problem when extending protocols in a mix of
inheriting and implementing classes...Let me explain:

Can anyone point me in the right direction?

Hi Karl,
I've added an experimental feature in tools.namespace 0.2.3-SNAPSHOT which
tries to recover the namespace configuration in your REPL after an error
during reload. What that hopefully means is you can call `refresh` as you
normally would even after an error.
Updated docs

Sorry about that, I just changed it to analyze 0.3.0, which is on Clojars.

As for dependencies:

to core.typed.

Hello,
I managed to get nrepl-ritz going, but I'm experiencing the following

still in action. Is there a way to disable it?

Stack analysis is quite a brittle mechanism, as far as I'm aware of. As
soon as you pass the object to any method, even if private, the object will
not be stack-allocated. The way Clojure code is typically written, and the
way it is compiled, some method call will almost certainly get involved.

Is this behavior specified? It certainly doesn't make sense from a
language user perspective.
^doubles can be used to avoid boxing on the hot code path, what would you

Actually, ^doubles can be used for two separate things, one of which
applies to ^objects as well: avoid reflection and avoid boxing/unboxing. I
do need to avoid reflection.

Thank you, I'm using it and it does work. However, there is presumably a
good reason for the existence of the ^objects annotation, so the question
remains whether this is a) specified behavior and b) the way it is planned
to stay.

I guess clj-http swallows the exception? It seems strange that it
doesn't bubble up to my code. But then I don't know Java so I probably
miss some of the etiquette about when a library should catch its own
exceptions.

This may be slightly off topic, but your longest contiguous common
subsequence problem sounds like the longest common substring problem.
Your code uses the dynamic programming solution, which is O(M*N), but
there are O(M+N) algorithms that might be faster depending on the length
and alphabet
It won't retry on http-level errors; those semantics are up to the
application. It should only retry connection-layer problems. So there must
have been something funny happening either between the client and Charles,
or between Charles and Omniture.

If you cut Charles out of the picture and just send your payload directly
