Using a dict of fields for arguments

Nobody has claimed this yet.

In the docs, I see there is a way to do: `@blp.arguments(PetSchema)`
Is there a way to simply do: `@blp.arguments({'name': ma.fields.Str()})` ?

I was trying to port some of my projects from flaks-apispec to flask-smorest and in flask-apispec I was doing: `@use_kwargs({'name': ma.fields.Str()})` a lot as that seemed generic and easy to define for my endpoints with simple query params.
I didn't see a similar thing in smorest, and was wondering if I have to define a schema every time ?

I don't like schemas too much because they become a bit verbose for 1 or 2 arguments ... and then in cases where I need borh a query-param and a body as arguments (POST with query params) I need to define 2 schemas - which seems to be confusing

Start with the blp.arguments entry point and the documentation describing PetSchema-based arguments, then compare the requested behavior with flask-apispec's use_kwargs pattern. Done means accepting a dictionary of fields for simple endpoint arguments, including cases combining query parameters and a body, with the behavior documented and covered by tests.
