# The [semantic
# highlighting](https://microsoft.github.io/language-server-protocol/specification#textDocument_semanticTokens)
# request informs the editor of the correct token types to provide consistent and accurate highlighting for themes.
#
# # Example
#
# ```ruby
# def foo
# var = 1 # --> semantic highlighting: local variable
# some_invocation # --> semantic highlighting: method invocation
# var # --> semantic highlighting: local variable
# end
# ```
