Hello.  I'm interested in fixing this bug:
http://dev.clojure.org/jira/browse/DJSON-21

data.json/read currently reads from the start of a java.io.Reader and as
soon as it has a read and parsed a complete form it returns it.  This is
good and logical but it leads to input like "123abc" being parsed
successfully as 123, which is confusing enough that the bug has been raised.

Whitespace after a form like that would be fine, (ie (read-str "   123   ")
=> 123).  So my questions:

- Is it a sensible idea to consume the Reader until EOF checking that
there's only whitespace remaining?
- Can we just live with this bug as-is?
- Is there a middle ground?  (eg checking the next n bytes for
non-whitespace then stopping)
- Would it make sense if we treat 'read-str differently from 'read in this
case?

  Thanks.

Matthew
