Merged
Conversation
Add TestParserRecursionDepth to measure stack memory consumption and crash boundaries when parsing deeply nested expressions in ANTLR vs Pratt parsers. ### Recursion Depth Comparison (Stack: 64 KB, Max Depth: 1000) | Category | ANTLR (Max Depth OK) | Pratt (Max Depth OK) | Pratt Advantage | | :--- | :--- | :--- | :--- | | **Parens** (`(((...42...)))`) | 20 | unlimited | **unlimited** | | **Unary** (`! ! ! ... true`) | unlimited | unlimited | **1.0x** | | **Binary** (`1 + (1 + (...42...))`) | 21 | 93 | **~4.4x** | | **List** (`[[[...42...]]]`) | 18 | 85 | **~4.7x** |
