The coverage of the unittests for std.json is 92%. But most of the uncovered 
lines should be trivial to cover with unittests. For example, JSON_TYPE.UINTEGER 
is completely untested.

A review of unittest coverage should be part of any review of new library code.

Note that checking the unittest coverage is as easy as:

     dmd std/json -unittest -main -cov
