Graphs aren't a huge application area, and can be viewed as a data type,
so I think the question being raised here amounts to: shall we abandon
the original idea of a strictly limited number of top-level nodes in
the module hierarchy, and move to a much flatter hierarchy?  That would
obviously make for shorter module names and make it easier to avoid
name clashes, but I think there's also value in having more structure
in module names, particularly at the top level.

In this particular case, the name-clash benefit would be a one-off.
And wouldn't it be better to take over FGL and evolve it rather than
