keyattr dynamic or AttributeError

[Loreton]

It's ok.
keyattr_dynamic=False should rise AttributeError also reading a not existing attribute.
Thank you Fabio

Ciao Fabio,
I believe that the default must be exactly like for the normal dictionary: False
So that accessing an undefined attribute gives an error. There should be no difference in results between the two access modes to the attribute value.
But this is just my thought.

@Loreton the keyattr_dynamic property is available in 0.30.0 version.

@Loreton I'm glad you enjoy this library and thank you for the useful feedback!

Example.1

The behaviour your reported is a direct consequence of having the possibility to create nested dicts using the chained dotted notation a.b.c.d.e.f without having an AttributeError.

Example.2

Attributes starting with _ are generally protected variables or dunder methods.
Some standard libraries use/check the presence of some protected variables and methods; the side effect is that some keys are created dynamically and the resulting dictionary contains unexpected keys (for a better understanding you could check #259).

I agree with the idea of adding a new option keyattr_dynamic=True: setting it to False would restrict the feature to write only already existing items otherwise an AttributeError is raised.

@Loreton what do you think should be the best default value for the keyattr_dynamic property, True of False?
