[swift-evolution] Thoughts on replacing \() with $() or some other symbol

[Goffredo Marocchi]

Sorry, but can you explain why the character used to   escape   strings is also the best choice to do   Variable value extraction/String interpolation?  They are two different concepts.

The "7" key says "7" and "/" - I'm talking about the German Mac Keyboard, the standalone version of the Mac Mini and the Notebook Version of Macbook Air/Pro are the same in this regard.), and "$" is written as Shift-4. "$" is used in languages were "$" is used as a sigil for variables. It makes sense there to allow these variables directly in some strings. But not so in Swift. What I like about "\" is that it is a compatible extension to string literals, as much as possible. Strings that were valid and sensible before are still valid and sensible and mean the same thing. You can copy&paste a C string literal into Swift, and it will have the same meaning, because C strings do not contain `\(`.
