Should we provide a way to embed/include a file dump as raw data?

A similar topic was discussed last year:

New literal for string from contents of file

Today, there are a number of literals that we can either use the IDE to generate or type by hand, such as: let red = #colorLiteral(red: 1.0, blue: 0, green: 0). Back in 2016, @Erica_Sadun pitched the idea to tidy up the syntax and add a bunch of new literals. I liked the idea, but it received some pushback for being too overreaching (that's my impression anyway). This is a much more focused pitch with a pretty clear use case and precedent in other languages. Please let me know what you think. …

But now that "SE-0271: Package Manager Resources" has been accepted, it might be better to think of .embed as another package rule (alongside the existing .copy and .process rules) to be applied to a file or directory path.

"Type-safe access to individual resource files" would then include support for embedded data.
