Parentheses supported by lexer but ignored by parser

[SAMBA8695]

Bug Report: Parser Does Not Handle Parentheses

Description

The lexer recognizes left and right parentheses tokens (( and )), but the parser currently ignores them entirely.

As a result, expressions that rely on parentheses for grouping are parsed incorrectly or fail to parse.

Example Input

let x = (1 + 2) * 3;

Although the lexer produces TOKEN_LPAREN and TOKEN_RPAREN, the parser never consumes or handles these tokens.

Current Behavior

• Parentheses tokens are generated by the lexer
• Parser does not handle ( or )
• Grouped expressions are not supported
• Expression evaluation order cannot be controlled by the user

Example

let x = (1 + 2);

Results in incorrect parsing or failure.

Expected Behavior

• Parentheses should allow explicit expression grouping
• Expressions inside parentheses should be parsed recursively
• Parser should consume matching ( and ) tokens
• Nested parentheses should be supported

Suggested Direction

• Extend expression parsing to recognize ( and )
• On encountering (, recursively parse an expression
• Ensure closing ) is required and validated
• Integrate with future operator precedence handling
