(read [reader] [{:keys [eof], :as opts} reader] [reader eof-error? eof opts])Reads the first object from an cljs.tools.reader.reader-types/IPushbackReader.
Returns the object read. If EOF, throws if eof-error? is true otherwise returns eof.
If no reader is provided, *in* will be used.
Reads data in the edn format (subset of Clojure data):
http://edn-format.org
cljs.tools.reader.edn/read doesn't depend on dynamic Vars, all configuration
is done by passing an opt map.
opts is a map that can include the following keys:
:eof - value to return on end-of-file. When not supplied, eof throws an exception.
:readers - a map of tag symbols to data-reader functions to be considered before default-data-readers.
When not supplied, only the default-data-readers will be used.
:default - A function of two args, that will, if present and no reader is found for a tag,
be called with the tag and the value.
