make uttrs superset of attrs?

[martinberoiz]

Can we make uttrs refer all unitless attributes to attrs? so that user doesn't need to juggle with both uttrs and attrs?
Some kind of superset of attrs?

[leliel12]

The fundamental idea of uttrs is to be an extension of attrs, and not a replacement. Adding more things would imply making a decision about two things:

1. To add more automatic behavior to classes (as proposed in # 4) we should redefine @ attr.s to something like @ uttr.s.
2. another alternative (maybe easier), would be to add code that makes an attribute with unit = None is equivalent to using attr.ib

Example

All the attributes are equivalent

@attr.s()
class Foo:
    a = attr.ib()
    b = uttr.ib(unit=None)
    c = uttr.ib()

I like all options
b) and c) could be done with a default keyword.
