Storing strings in JSON::Any variables not working

I recently got back into crystal and I noticed some breaking changes concerning JSON behaviour in 0.25.0.

Previously, when I had a variable of type JSON::Type, I could simply store a string in it

a : JSON::Type
a = "some string"

this is no longer possible after changing the variable to JSON::Any, resulting in an error: type must be JSON::Any, not String

However, calling .to_json or as(JSON::Any) on the string also does not work because the returned value is also of class String.

puts typeof("Hello".to_json) => String
puts typeof("Hello".as(JSON::Any)) => String

Is this intended behaviour? How do I now store strings in json?

Also, locally, for JSON.parse("some string") I get a JSON::ParseException, while it works online... https://play.crystal-lang.org/#/r/4y49

The correct usage is now JSON::Any.new("some string")
