# [Inlay hints](https://microsoft.github.io/language-server-protocol/specification#textDocument_inlayHint)
# are labels added directly in the code that explicitly show the user something that might
# otherwise just be implied.
#
# # Example
#
# ```ruby
# begin
# puts "do something that might raise"
# rescue # Label "StandardError" goes here as a bare rescue implies rescuing StandardError
# puts "handle some rescue"
# end
# ```
