Built in Rust on top of ts-parser-perl and tower-lsp. Witness bags with graph traversal (value edges, call flow edges).How it works: - builds witnesses and scopes by walking the parse tree. Fully known values get concrete types, otherwise they get an edge pointing to the last witness we have for this symbol - a worklist runs to a fixed point: reducers fold each symbol s witnesses and chase edges. At this point, the witness bag is complete and ready to use - all downstream features are queries into the bag, following along the graph edges that are relevantExtensible - you can bring your own Rhai plugin to shortcut common patterns (exporters and OOP frameworks), or even add new types of definitions (worker tasks and web routes).The build/query timing distinction with edges let s you late bind types, which is duly similar to how Perl itself works: `Foo- new` isn t known if it s the constructor for Foo or calling a method on the sub name `Foo`; late binding lets you make that call after the worklist folds.
