1. Exception handling with generators is not fully implemented. (Some small details may need to be done yet.) [#243](//github.com/micropython/micropython/issues/243)
1. str.format() may miss few advanced/obscure features (but otherwise almost completely implemented). [#407](//github.com/micropython/micropython/issues/407), [#574](//github.com/micropython/micropython/issues/574)

1. Instead of ``re`` module, minimified "ure" module is provided is subset of functionality. micropython-lib also offers more complete implementation based on PCRE engine, for "unix" port [#13](//github.com/micropython/micropython/issues/13)
1. Only beginning of ``io`` module and class hierarchy exists so far.
1. ``collections.deque`` class is not implemented.
