19543	SimpleLazyObject missing __repr__ proxy	spinus	fhahn	"SimpleLazyObject (from django.utils.functionals) does not proxy _repr_ method.
Use Case:

{{{
User.__unicode__ -> print data for user, example: ""user@email.com""
User.__repr__ -> print debugging data, example: ""<User pk:1, email:user@email.com, points:123>""
}}}

_unicode_ is used by most of application to render user content so I cant override it to using at logging. _repr_ is used in logging. 

Example user message: ""Hi %s""%request.user
Example logging message: ""%r just logged in""%request.user

When user is wrapped with SimpleLazyObject _repr_ method of User is not called. 
My idea is to make it available like

SimpleLazyObject._repr_ = lambda self: '<SimpleLazyObject: %r>'%self._wrapped
