Pratt parsing definition for expression parsing Pratt expression parser definition.

IMPORTANT: The parser generator does NOT handle whitespace automatically. All whitespace handling must be done explicitly in the grammar DSL. This includes whitespace between operators and operands.

For expressions with postfix operators followed by infix operators (e.g., “a.x * b”), the grammar must ensure whitespace is consumed. Common patterns:

1. Have the operand rule consume surrounding whitespace
2. Use pattern-based operators that include whitespace in their patterns
3. Structure the grammar so postfix chains are parsed as complete units

DO NOT add automatic/hardcoded whitespace handling to the parser generator.
