Yes, eg: https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/O=
RM/EntityRepository.php=23L24

it could be:
from Doctrine=5CCommon=5CCollections use ExpressionBuilder, Criteria, Arr=
ayCollection, ExpressionBuilder;

The Motivation is that I found many projects that use namespace have the =
problem of repeat type
the same namespace again and again. =20

I think it could be useful to reduce duplication, but not copy everything=
 from Python.
like many useful features we borrowed from other languages ;-)

Yes, introduce new features may break things, eg the new trait,insteadof =
in 5.4, and maybe =20
the comming finally, yield etc. but if it is desired, I think it may wort=
h it. =20

Thanks for your feedback=21
