# Things to Do in the future

# After mruby 3.1

- parser and code generator independent from `mrb_state` (picoruby?)
- variable sized AST node
- iv/hash entry cache
- more peephole optimization (if possible)

# Things to do (Things we need to consider)

- `begin ... end while cond` to behave as CRuby
- special variables ($1,$2..)
