Thanks, good suggestion. Fixed in trunk.
Originally (pre-release versions of) CQEngine did use Iterable here. The reason
for requiring List was the algorithm in TupleCombinationGenerator (used by
CompoundIndex). Most literature talks of Lists :) But on revisiting it today,
the inner lists can actually be Iterable, so it was easier than expected to
refactor.
Indeed this change can provide more flexibility and performance improvements in
applications.
These changes are backward compatible with existing attributes at source code
level, but they are not backward compatible with already-compiled attributes.
When applications upgrade to the next release of the library, existing
attributes will need to be recompiled against the new Attribute interface;
however no actual code changes in the attribute source will be necessary.
The changes are in trunk, but I will leave this issue open until the next
release is out.
