Current behavior

Hello there! I'm using Elixir code formatting, so I checked the implementation of Code.format_string!/1, and it wraps all literals in __block__. Besides formatting, I'm sorting map keys with an AST traversal, and using Macro.quoted_literal?/1 to split computed and literal keys, but it's returning false for the wrapped literals. Is this the expected behavior?

Expected behavior

Should Macro.quoted_literal?/1 return true for literals wrapped in __block__?

__block__ should return true if it is a single element block with a literal in it. Please send a PR indeed!
