NEW (AND UPCOMING) B++ CHANGES

Tokenizer

• Added inline comment support (#) outside of strings.

• Correctly handles escaped quotes inside strings (\").

• Preserves line numbers for better error reporting.

Expression Evaluation

• Supports more literal types via ast.literal_eval: strings, numbers, booleans, lists, tuples.

• Added fallback safe eval for advanced expressions.

• Smarter + handling: concatenates strings if any operand is a string, otherwise performs numeric addition.

Conditions

• Added support for == and != (was missing before).

• Full set of comparison operators now: is, is not, <, >, <=, >=, ==, !=.

• Falls back to truthiness check if no operator matches.

Block Handling

• Fixed bugs with if/elif/else nesting.

• elif and else no longer incorrectly increase nesting depth.

• Cleaner and more reliable collect_block parsing.

Math and Variables

• Division automatically converts integers back (10 / 2 → 5 instead of 5.0).

• Safer error messages when adding or multiplying incompatible types.

Extra Features

• New import module support (with identifier safety check).

• --debug mode: shows environment after each line.

REPL

• Introduced start command to run buffered code explicitly.

• Improved block depth tracking for multi-line blocks.
