Bugs

• Newlines in multi-line string tokens are not processed by lexer
• If definition of blocking native function change while it is paused, new version will be invoked upon resume
• Function constant pools use === for equality - results in duplicates of any values whose internal representations are objects e.g. colors

Language Features

• Fix/finalise scoping rules
• REPL
• Control flow - break/continue
• Name mangling
• Arrays
• Dictionaries
• Spawn
• "Garbage collection"
• stdlib

Debugging tools (browser-based)

• Inspector (function browser, bytecode explorer/decoder)
• REPL
• Timeline
• Callstack visualiser
• Breakpoints
• Interaction with live stack-frame

Internals/optimisations

• Compiler flag - auto-yield insertion
• Compiler flag - name mangling
• Constant folding - see http://bugs.python.org/issue1346238
• Dead code removal
• Inline method cache
• (possible) Implicit return is possible through syntax tree analysis and planting returns in the correct places. This would remove the need for 2 opcodes and save one memory write per statement. Probably best leave this until we've got some machinery in place for walking/transforming the AST.

Tooling

• Editor integration

Future Roadmap

• Closures
• List comprehensions
• Object system, maybe
