feat(parser): support turbofish operator and specialize access expressions
Signed-off-by: erick-alcachofa <erick@artichoke.dev>

Overhaul the AST and parser logic to support explicit generic
instantiation in expressions (e.g., `Result::<u32, u32>::Ok(0)`). This
is achieved by implementing the "turbofish" operator (`::<>`) and
specializing how member and module access are handled.

* Added `GenericExpression` to represent generic instantiations in
  expressions.
* Updated the Pratt parser to look for `<` immediately following a `::`
  (ModuleAccess) operator. If found, it parses a `GenericExpression`
  containing the generic arguments.
* This change resolves the ambiguity between generic lists and
  comparison operators in the expression parser.

* Renamed `PointerAccessExpression` to `PointerMemberAccessExpression`.
* Refactored `MemberAccessExpression` and
  `PointerMemberAccessExpression` to store the member as an
  `ExpressionNode`. This allows the right-hand side of a `.` or `->` to
  be a complex expression (like a generic call).
* Simplified `ModuleAccessExpression` to a binary `left`/`right`
  structure, separating scope resolution from generic instantiation.

* Flattened the `Type` AST: replaced recursive `baseType` structures
  with a `Vector<TypeExpressionNode>` (`typeNodes`) to represent
  namespaced paths (e.g., `std::collections::Map`) more efficiently.
* Removed redundant `NamespacedType` and `NamespacedIdentifier` nodes.
* Simplified `GenericType` and `IdentifierType` to use direct `String`
  type names.

* Refactored `parseType` to iterate through namespaced components and
  populate the new flattened `typeNodes` vector.
* Updated the Pratt infix loop to correctly dispatch to `ModuleAccess`,
  `MemberAccess`, or `GenericExpression` based on the operator and
  lookahead tokens.
* Adjusted `toDot` and `toString` visitors to match the new AST
  definitions.

⚠️ WIP Highly Experimental Project

  • The language, compiler, and tools are under active development and may be very unstable.
  • There will likely be breaking changes and periods where no work is done on the project.

The artichoke Programming Language

artichoke is a modern, statically-typed programming language designed to satisfy my personal preferences and requirements for programming, combining the low-level control and powerful modern features like a robust type system, generics, integrated error handling, and a clean, ergonomic syntax.

The goal of artichoke is to provide a language that is simple, safe, and productive for programming, eliminating common pitfalls without sacrificing performance or control.

For a detailed guide to the language, please see the project wiki.

Core Philosophy & Features

artichoke is built around a few core principles to create a safer, more productive programming experience:

  • Explicitness: Type conversions and error handling are explicit.
  • Safety: Non-nullable pointers, a robust type system, and deterministic resource management are prioritized.
  • Modern Ergonomics: Features like generics, defer, and a clean module system reduce boilerplate and improve readability.

The language includes a powerful generic type system, first-class error handling, a full suite of control flow statements (including match), a true module system, and compile-time reflection.

Project Status

artichoke is currently in the design and grammar-specification phase. The grammar is stable, and the next step is the implementation of a compiler (parser, semantic analyzer, and code generator).
