Good idea, but I’d rather keep the attribute name out of the curly braces.
Even if this is not supported by the Elixir compiler, I’ll be able to support it through the template parser. The keyword list square brackets can be added automatically if special cases are detected, and the Elixir compiler will still be used to validate the final code since the template is a regular sigil macro. However, we won’t be able to say that everything inside the curly braces (or including the braces) is a valid Elixir code.
