tri.struct supplies classes that can be used like dictionaries and as objects with attribute access at the same time. There are two versions:

• Struct: mutable struct
• FrozenStruct: immutable struct

Some niceties include:

• Predictable repr() so it's easy to write tests
• merged function call to merge different types of dicts into a new: merged(Struct(a=1), FrozenStruct(b=1), c=1) == Struct(a=1, b=1, c=1))
• Accelerated implementation in c for improved speed. (With python-only fallback reference implementation)

>>> from tri_struct import Struct
>>> foo = Struct()
>>> foo.a = 1
>>> foo['a']
1
>>> foo['a'] = 2
>>> foo.a
2

You need tox installed then just make test.
