The licence is GPLv3+ because the code is closely influenced by
igraph, which is GPLv3-licensed. It's not like there's
copy-pasting, but it's not clean-room either, so offering a
permissive licence might put users in an invidious situation if
the igraph authors chose to make an issue of it. Unlikely, but
better safe than sorry.
If anyone wants to use it in a commercial application the best
thing probably to let me know and I can discuss with the igraph
authors. I will probably do so anyway once the library is more
feature-complete, less out of concern for commercial apps than
in order not to be incompatible with other free licenses.
I see. You can use Boost Graph Library (BGL) as a initial point.
It's under Boost license that allows commercial usage.

Also, it would be nice to have graph library in Phobos in a
future, and in that case module must be under Boost license.
But yes, you can try to contact igraph authors - maybe they let
you change the license.
