wraps fails on decorating objects that miss or does not support __dict__ manipulation

[tokarenko]

Call to wraps fails on decorating objects that miss __dict__ or do not support __dict__ manipulation. E.g. classes or special methods (e.g. __setattr__). Please consider this solution and/or adding 'updated' option as in functools.wraps (with 'updated=()' functools.wraps doesn't have this error).

I would be grateful if you could advise on feasibility of using wraps on decorating special methods. Does it make sense to youse wraps in this case?

@wraps(validated.__setattr__)
.venv/lib/python3.11/site-packages/makefun/main.py:874: in wraps
    func_name, func_sig, doc, qualname, co_name, module_name, all_attrs = _get_args_for_wrapping(wrapped_fun, new_sig,
.venv/lib/python3.11/site-packages/makefun/main.py:964: in _get_args_for_wrapping
    all_attrs = copy(getattr_partial_aware(wrapped, '__dict__'))
.venv/lib/python3.11/site-packages/makefun/main.py:110: in getattr_partial_aware
    val = getattr(obj, att_name, *att_default)
E   AttributeError: 'wrapper_descriptor' object has no attribute '__dict__'

Thanks @tokarenko for the proposal !

@wraps is nothing but a customized @with_signature so that all dict editing work is automatic.
So if you just want to modify the signature and not the __dict__ you should probably use @with_signature directly. This should work even on objects that do not have settable attributes I think. If not please provide a reproducible example, I'll check what I can do.
