Behavior with aliases

[art049]

Hello, I'm thinking to enable the aliases on the fields. It would enable a cleaner attribute validation to avoid conflicts between builtin methods and the fields for example (as already done by Pydantic).

The current behavior I'm thinking of:

• If a field has an alias and no key_name, the resulting document key will be the alias
• It's still possible to customize the key_name with an alias already set by specifying the key_name kwarg

Do you think some more customization/options would be useful ?

Customization would be very helpful.

Preferred behavior in my opinion:

• An object creation are possible from dict with alias/field keys, but document creation itself should be regulated using parameter like by_alias , that pydantic's dict method already have.
