Multiple let statements not supported

[SAMBA8695]

Bug Report: Only One Top-Level Statement Supported

Description

The compiler currently supports only a single top-level let statement.

After parsing one declaration, the parser stops and ignores any remaining input.

This prevents writing programs with more than one statement.

Example Input

let x = 1;
let y = x + 2;
let z = y + 3;

Only the first let statement is parsed and compiled.

Current Behavior

• Parser handles only one top-level statement
• Remaining tokens after the first statement are ignored
• No program-level AST structure exists
• Multiple declarations are not supported

Expected Behavior

• The compiler should support multiple let statements
• Statements should be parsed sequentially until TOKEN_END
• A program should consist of a list of statements
• Each statement should be processed in order

Suggested Direction

• Introduce a program or statement-list AST node
• Parse statements in a loop until TOKEN_END
• Store statements in an array or linked list
• Update IR generation to process all statements sequentially
