Is there an elegant way of expressing multiple-dispatch (with support

get-length can be called by any map who's :class is derived

I also thought it was in the language and I just didn't know the name. Good

And "do-with" sounds like a good name to me.

Rich,
I just wanted to thank you for your presentation at Lisp50. The
excitement that was created from your presentation was amazing. I
believe that this is the beginning of a resurgence of Lisp in the
market and I think Clojure is leading the way. After last nights

Thank you for considering adding this to Clojure. I actually wrote
this macro myself, but I've always thought it was in the API already
and I just didn't know what it was called.

I vote for "do-with" too.
I used to upgrade my Ruby runtime with Ola Bini's Kernel::with.
It could be used exactly the same way as proposed do-with. However,
do-with is more idiomatic name, IMHO.

Since there is now a movement afoot to write a comprehensive test
suite, I want to re-post the spike I did earlier on ClojureCheck.
It would be cool to use check-style tests for at least part of the
Clojure suite. If there is interest in this, I hope to have time to

Hi,
recently I ran in the a limitation of doto, that it only invokes
methods. However piping the object with -> does not work
also, since it's semantics are more like .. .
