This gives me an excuse to revisit smithy. Curious if editor support is still poor in VSCode. Last time I cracked it open, I found that (1) there was no AST introspection and (2) existing language support tooling was lacking modern features (click to definition, autocomplete of ambient/imported smithy types). (2) made me attempt to write a language server and I stopped when I realized there was no easy way to hook into the parser.
