Im using Clojure 1.7

[mschuene]

expresso 0.2.2-SNAPSHOT works with 1.7. I updated the readme to use this version.

[dmh43]

@mschuene I haven't been able to get the tests to pass with any version of Clojure later than 1.6. It looks like one issue is the addition of cat in 1.7 which seems to conflict with an instaparse var in version 1.3. When requiring expresso from a Clojure 1.7 project, I get CompilerException java.lang.Exception: namespace 'instaparse.abnf' not found, compiling:(instaparse/core.clj:1:1). Any ideas how to move forward with this?

[gcbeltramini]

Adding instaparse to the leiningen dependencies made it work in Clojure 1.8:

:dependencies [[org.clojure/clojure "1.8.0"]
               [expresso "0.2.2-SNAPSHOT"]
               [instaparse "1.4.3"]]

[dmh43]

@gcbeltramini awesome! I'll try this.
