This commit introduces fundamental changes to Myc's language structure
to enhance type safety and scoping clarity.
Key changes include:
- Introducing local scopes for `do` blocks.
- Separating statements (`def`, `assign`) from expressions, where
statements now have no return value and are only allowed within
blocks.
- A block now consists of multiple statements followed by a single final
expression.
- Stricter validation rules are enforced, such as disallowing
redefinition of local symbols in the same scope while allowing
shadowing of outer symbols.
- Compiler errors are generated for statements used in expression
contexts.
The implementation involved modifications to the AST, parser, binder
(scope-stack), and various compiler passes, along with VM runtime
optimizations.
This commit updates the benchmark and repeat counts for various example
files. These changes reflect potential performance improvements or
variations observed during testing.
Introduces type specialization for reactive pipeline nodes and their
data buffers. This eliminates the overhead of generic `Value` enums and
`SharedValueSeries` when dealing with known scalar or record types.
The architecture shifts buffer instantiation from the VM to the runtime
(RTL), leveraging type information from the AST. A new `out_type` field
is added to `BoundKind::Pipe` to store the static type of the pipeline's
output, determined by the type checker.
This enables the creation of specialized `RingBuffer<T>` and
`SharedRecordSeries` (for Struct-of-Arrays layout) when the output type
is known, significantly improving memory usage and processing speed for
time-series data, especially in financial analysis.
This commit updates the benchmark results for various examples. The
benchmark times and repeat counts have been adjusted to reflect current
performance characteristics.
