Shaking out clojure.data.json's own test suite (now 134/137):
- Reader.read(char[],off,len) bulk read + PushbackReader.unread(char[],off,len)
on the string/pushback reader jhosts; instance? java.io.PushbackReader/
Reader/StringReader (data.json re-wraps a reader unless it's already a
PushbackReader, so this is load-bearing for repeated reads).
- number protocol dispatch by actual type: a flonum is Double (not Long),
exact ratio is Ratio, exact integer is Long — value-host-tags split.
- Integer/toHexString|toOctalString|toBinaryString|toString; .isNaN/.isInfinite
as instance methods on numbers.
- EOFException ctor/class; .isArray on a class-name string.
- dispatch tags for the uuid/bigdec/inst host values so a protocol extended to
java.util.UUID / java.math.BigDecimal / java.util.Date / java.time.Instant
reaches its impl; canonical-host-tag strips java.math./java.time.
- instant/zoned/local time values compare = by epoch-ms (two parsed Instants).
- java.time.Instant/parse, java.sql.Date ctor + valueOf, TimeZone/getDefault,
DateTimeFormatter/ISO_INSTANT.
