correctly initialize the `TypeChecker` with argument types during
macro expansion.
- Refactor `Specializer::compile` to perform type checking with provided
arguments before specialization and to correctly extract the return
type.
- Enhance the `Dumper` to introspect and display specialized closure
bodies.
- Update `LambdaCollector` to use `BoundNode` consistently.
- Modify `TypeChecker` to accept and inject specialized argument types
for lambdas.
This commit introduces support for AST macros and templates, enabling
users to define and use custom, reusable components within the visual
DSL.
Key changes include:
- A new `MacroRegistry` to manage macro definitions.
- A `MacroExpander` to process macro calls and expand templates.
- A `MacroEvaluator` trait for evaluating expressions during expansion.
- The `Expansion` node in `BoundKind` to preserve the original macro
call and its expanded form for debugging.
- Updates to the `Binder`, `Dumper`, and `UpvalueAnalyzer` to handle the
new macro constructs.
- New examples demonstrating various macro functionalities like
`unless`, splicing, and nested macros.
