This is really cool. It's great to see someone pushing for good desktop applications. I'm not an electron hater, but I don't love it either, and I'm happy to see new alternatives emerge, in a fun language like clojure no less.
Maybe it's a question of personal taste, but Pascal (in any of its newer forms) isn't a langauge I like working with. Up-front variable declaration, verbose flow control, next to no support for functional programming... LCL is nice, I especially like how small the result is, but in the last ~30 years, programming language design has progressed a lot and Pascal just seems archaic, and not in a good way. Modern PL design isn't just about "syntax sugar" as the FreePascal community would have you believe.
