coerce and nullable

[kseniyam]

The behaviour changed:

ID_SCHEME = {'_id' :{'type':'string', 'coerce':str, 'regex': r'[0-9abcdef]{24}', 'required':True, 'nullable':True}}
_id = {'_id':None}
v = Validator()
print(v.validate(_id, ID_SCHEME))
print(v.errors)

in version 9 this gives:
True
{}

and in version 10 the same gives:
False
{'_id': "value does not match regex '[0-9abcdef]{24}'"}

Is this intended change?

i don't think any of both behaviours was intended.

nonetheless i'd consider the recent as 'correct'. you can either extend your regex and dismiss the nullable-rule or implement #102 for a more clever coercion.

if you can omit the coerce-rule it should work as well. if i remember right, allowed None-values are not validated in-depth.
