/usr/local/lib/ruby/gems/2.4.0/gems/edn-1.1.1/lib/edn/core_ext.rb:97: warning: constant ::Bignum is deprecated

[trevor]

Bignum has been removed in Ruby 3.2, this now causes an error instead of a warning.

[jgomo3]

This error would be fixed with the PR #42

In particular with this change https://github.com/relevance/edn-ruby/pull/42/files#diff-61ff3de53f862ec463867dc7587198545543f65a5c1103ded35d660002f08626

That change simply removes the extension to the Bignum module, which doesn't exist anymore.

@jgomo3 From all appearances the @relevance organization is no longer a going concern.

Have a look at https://github.com/edn2023/edn2023 and https://github.com/edporras/edn_turbo for EDN support in Ruby.
