The intention of the string interpolation DIPs so far is not necessarily to generate strings but to give a mechanism to overload for string interpolations. So the Also, other string types do not have escape sequences. -Steve | |||

The proposed exemple is simply terrible code as it allows for shell injection. It depends on the executeShell function that accepts interpolations. It could just text-ify the thing (convert to a string) or properly escape anything in the interpolation portions. Granted, the DIP does not discuss this possibility. >One of the motivating example is SQL prepared statements, but once again, replacing this by the proposed string interpolation means SQL injection. No, it doesn't. This tells me you are missing something in your understanding of the proposal. -Steve | |||

An improvement over:
? It obviously isn't! What is that sql function doing? It's not just concatenating strings, and it's also not anything I would ever want to use, in original or interpolation form. It appears to suggest it's going to happily do sql injection as well. >This will end up being a marginal feature. For this fictitious example, maybe. But I already see huge potential in my real actual libraries that I've written. You don't have to use it if you don't want to. -Steve | |||

The proposed exemple is simply terrible code as it allows for shell injection. You say you read it, then say something that is blatantly false about it. This dip does NOT produce strings. It produces argument lists. The receiving function knows what was part of the string literal and what were arguments and can process them accordingly. But don't you think it would be better if you could write: [...] Love the idea of having type-safety with this!
