Hi Toby, There is an outstanding issue with JSON::Path which includes a pull request to fix https://github.com/tobyink/p5-json-path/pull/1
The issue is that JSON::Path only supports the dot operator for the jsonpath specification, and doesn't allow use for the square bracket with quote method. Dot notation: $.store.book[0].title Bracket notation: $['store']['book'][0]['title'] Both are valid. If you're defining the definitions yourself, you can avoid the unsupported functionality, but this is not ideal for an interoperable API. Would you be able to accept the pull request and push out a new release? If not, would you be able to issue me with co-maint, like with JSON::Schema previously?
