First of all, thank you for accepting the proposal. However I still have one single concern left about the trailing whitespaces. Will the final implemented version raise a warning or produce an error when there are trailing whitespaces?
The whole idea of a trailing \ was in first place to prevent new line injection but also for trailing whitespace character precision.
The following example could have 1000 characters, but a different developer who reads the code wouldn’t even notice.
That’s what the trailing backslash was meant for. To prevent unwanted whitespaces, or if you really need them, to force you to be precise about them.

- It should be clarified that multiline strings support the same escapes and interpolations as single-line strings. This allows a literal """ to be written \""". Discussion on the list raised the idea of allowing a line to end with \ to "escape" the newline and elide it from the value of the literal; the core team had concerns about only allowing that inside multi-line literals and felt that that could also be considered later as an additive feature.
