Given that there's already support for "fixed table" maps, which are essentially ordered maps, the implementation of OrderedDict just extends "fixed table" maps by adding an "is ordered" flag and add/remove operations, and reuses 95% of objdict code, just making methods tolerant to both dict and OrderedDict. Some things are missing so far, like CPython-compatible repr and comparison. OrderedDict is Disabled by default; enabled on unix and stmhal ports.
