really excited to see what you are working on! i made a docblock parser a while back, but did not dive deeper into type parsing :)

the secret sauce is really just using the regular PHP lexer to process content inside of a docblock, then applying parser rules and expectations to consume text as per the grammar. that'll then get pulled into the workspace indexer for better type info.

the first iteration of the static analyser is only going to focus on typechecking, and I'd like to do some "proper" type inference too so that even poorly typed code is capable of being checked.

basically, I want the type checking to be as powerful as possible without _needing_ docblocks

The majority of DocBlock parsers work on already parsed code, or just raw comment strings.

PXP is unique as it parses the DocBlocks at the same time as regular PHP code. Surprisingly, this is more performant as it doesn't need to traverse the entire AST to analyse and process DocBlocks!

I could potentially use this as a lib I maintain does heavy docblock parsing.
