optional nit: GetStateProperties could merge only omit the initial clear().

[stevenjb, 2014/05/15 20:12:41]

While that is probably safe currently, and I could document the behavior, I
still worry that it would potentially lead to a re-used local unintentionally
combining states. (I'd want to rename it MergeStateProperties at that point,
similar to DictionaryValue).

optional nit: limit could also be forwarded to GetFavoriteListByType (down to
where the filtering happens)

[stevenjb, 2014/05/15 20:12:41]

Moved limit to GetFavoriteListByType (and changed + documented that 0 == no
limit)

I'd find it more logical if the condition would be at the beginning, which would
also work for limit=0 ;-D

(the loop condition is also evaluated at the beginning of each iteration)

[stevenjb, 2014/05/15 20:12:41]

meh
