FAQ

How does this module compare to other JSON modules on CPAN?

As of version 0.04, performance-wise this module quite on par with JSON::PP (faster on strings and longer arrays/objects, slower on simpler JSON) and a bit slower than JSON::Tiny. And of course all three are much slower than XS-based modules like JSON::XS.

JSON::Decode::Regexp does not yet support Unicode, and does not pinpoint exact location on parse error.

In general, I don't see a point in using it in production (I recommend instead JSON::XS or Cpanel::JSON::XS if you can use XS modules, or JSON::Tiny if you must use pure Perl modules). But it is a cool hack that demonstrates the power of Perl regular expressions and beautiful code.
