Thank you, so many great features. My personal favorite is .declLiteral() syntax, which makes webserver route-configuration very easy and readable!
If you are ever in temptation to do a builder for internal DSL, .declLiteral() might be a better way. I think it might be very cool for GUI structures too.
I did a quick PoC for SQL query building, but unfortunately, any more advanced queries are better to copy & serialize their arguments for safety reasons, so not that useful there, but still, very hyped about this particular thing.
