I feel the hard part about jumping from something like C# to something like Gleam isn't the syntax, it's learning the semantics. once you learn the semantics, it's easy to pickup new syntaxes, regardless of the language.
I think much of the same badass code completion would be possible, if we have a live system with real objects to code against.
