[bitbake-devel] [master][PATCH 3/3] bb.data_smart: use iter() for __len__

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

It seems the frozenset constructor in pypy runs len(), so we can't pass the
DataSmart instance directly to it, instead pass the iterator. Fixes pypy
support.
