This commit introduces a new AST analysis pass that identifies function
purity and recursion. This information is then used by the optimizer and
specializer to make more informed decisions, particularly regarding
inlining.
The `Analyzer` struct and its associated `Analysis` struct are
responsible for traversing the AST and collecting this data.
Key changes include:
- A new `analyzer` module is added to `ast::compiler`.
- `Analyzer::analyze` performs a two-pass traversal to collect
global-to-lambda mappings and then analyze purity and recursion.
- The `Optimizer` and `Specializer` are updated to accept and utilize
the `Analysis` data.
- Recursion checks in `Optimizer` and `Specializer` are replaced with
checks against the pre-computed `Analysis.is_recursive` set.
- The `Environment` now stores and passes the `Analysis` results to the
compiler stages.
Introduces a new optimizer pass that can "crack" closures, allowing for
more aggressive specialization. It also enables inlining of upvalues
that point to immutable global variables. This removes overhead for
higher-order functions and currying when arguments are statically
resolvable.
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.
