Github user StephanEwen commented on the issue:

    I see no problem with merging this, from a code perspective.
    I do not completely get all the mechanics and reasoning behind this, so would be great
if @vasia could comment on this.

>          Components: Gelly
>    Affects Versions: 1.1.0

>             Fix For: 1.1.0
> Complex and related algorithms often overlap in computation of data. Two such examples
> 1) the local and global clustering coefficients each use a listing of triangles
> 2) the local clustering coefficient joins on vertex degree, and the underlying triangle
listing annotates edge degree which uses vertex degree
> We can reuse and rewrite algorithm output by creating a {{ProxyObject}} as a delegate
for method calls to the {{DataSet}} returned by the algorithm.
