Dear Clojurians,
Inclusion of such questions on the survey would be another opportunity
for Clojure to be more than just not unwelcoming to atypical folks and
allow us to purposefully invite more people to this relative paradise we
inhabit.
I would simply not fill the survey. Because what

Can you still tell me what the problem statement is? I saw some

Hi,
I have the opportunity to start some clojure here in our office, we are a

I’d like to offer an alternative implementation of clojure.core/transduce.

This alternative is best motivated by example. Consider the following

I know when I send/send-off an action to an agent within a STM transaction

I was expecting similar behaviour when agent fails: the transaction does

Hi,
The issue is that you can't use clojure.core/for in typed code.
You must use clojure.core.typed/for
http://clojure.github.io/core.typed/#clojure.core.typed/for, and annotate
the parameters and expected type.

Thanks Ambrose,
It makes way better sense after looking at your gist. I still don't *quite*

to the data structure that comes after it?
This is a super cool project, by the way.

The :- is just a bit of syntax to signify an annotation. As a rule, it goes
*after*
the form you might expect to attach metadata to.
eg. (t/fn [a :- Int] :- Num ) is [Int - Num]
(t/let [a :- Int, 1] ...) checks 1 as being under Int.
(t/let [[a b] :- '[Num Num], [1 2]] ...) checks
There are primitive vectors. Extraordinary clever.

That's much clearer now. Thanks a lot.
