+1. ``struct`` module implementation (named ``ustruct``) should have all basic functionality, but misses some syntactic sugar (like repetition specifiers in type strings). It's named differently to allow implement full ``struct`` functionality on Python level.
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)
