This commit introduces a detailed analysis of the Delphi Reactive Stream
Pipeline architecture, contrasting it with the current Rust
implementation. It outlines the core concepts of Delphi's stateless
streams, `TStreamSignal`, `TRootStream`, `TPipeSource`, `TScalarSeries`,
and `TPipeStream`, emphasizing their roles in event propagation, state
management, and synchronization.
The document also details the integration of the `pipe` statement within
the Delphi AST and compiler pipeline, covering the parser, AST
structure, type checker, and evaluator.
Finally, it proposes a "Dual Series Architecture" for Rust,
differentiating between script-local `RecordSeries` (for accumulators)
and reactive `SharedSeries` (for the pipeline), and outlines a concrete
implementation plan.
