Support for spec/assert?

[nwjsmith]

Thanks for expound, it's a great addition to spec.

I've been using clojure.spec/assert in combination with Clojure's pre-conditions. Would you be interested in a PR which adds support for assertions, or is that out-of-scope for expound?

@nwjsmith Good idea! I'm working on a PR which will add support for a number of spec features, including assert. Once that lands in master (hopefully this week), can I check back in with you and see if it would work for you?

[nwjsmith]

That would be fantastic. Let me know if I can help in any way.

@nwjsmith Would you mind trying this feature before I release?

To try it:

1. git clone git@github.com:bhb/expound.git
2. cd expound
3. git checkout expound-printer
4. lein install
5. In client project, change dep to [expound "0.1.2"]

I have chosen not to add an assert function directly to Expound. I may change my mind on this, but for now, I'd like to avoid mirroring the various functions in spec.

Instead, you can set the *explain-out* var like so:

(s/check-asserts true)
(set! s/*explain-out* expound/printer)
(s/assert :example.place/city 1)

Excellent, that works for me. Thanks!

@nwjsmith Thanks for reporting this and for testing the fix!
