Re: [ANN] Clojure 1.10.1-beta1

D'oh! Sorry, I messed up. With the correct vector present I'm getting this 
then:

Don't know how to create ISeq from: clojure.lang.Keyword

Seems like you can optionally enable spec so that you'd get:

:all - failed: coll?

which is better, at least pointing in the general direction of the problem.

Re: [ANN] Clojure 1.10.1-beta1

2019-03-31 Thread Rakhim Davletkaliyev
Hi Alex,

With this beta + ClojureScript (v. 1.10.238), when trying to "refer all", 
like so:

(:require trybeta.something :refer :all)

I get the following error:

clojure.lang.ExceptionInfo: Only [lib.ns & options] and lib.ns specs 
supported in :require / :require-macros; offending spec: :refer at line 1 
 {:file "", :line 1, :column 1, :root-source-info 
{:source-type :fragment, :source-form (ns trybeta.core (:require 
trybeta.something :refer :all))}, :tag :cljs/analysis-error}

This is much better than "Don't know how to create ISeq from: 
clojure.lang.Keyword" error present in previous versions!

While I completely agree that "require all" is bad style and should not be 
used, I think the error message could be a bit more specific still, 
considering "refer all" is quite widespread in tutorials/examples, and 
beginners like myself tend to try to use it when transitioning from Clojure 
to ClojureScript.

Maybe, isolate and display the offending part?

I apologize if this suggestion is irrelevant, as I am out of my depth when 
it comes to core Clojure and spec.

Thank you!
