Hi, I'm the lang designer here.
We looked into this. However, there didn't seem to be any benefit to this above just the N-quote version (which fits into how C# does strings everywhere else). In the above case, the `SQL(` and `)SQL` tokens are just akin to N-quotes. Since there's no additional benefit, we went with the simpler approach that solves all these needs, but will look the same across all codebases.
