Hi,

I have my own container and define a wrapper around it to make it behave like a BGL graph. Is it possible (and does it make sense) to define wrapper for bundled properties i.e. I want to control the storage of the bundled properties but want the expression to evaluate

   G[n].color = white

As of now, I will just get an error operator [] not defined. It is quite that I just need to define operator  [] for G. Thanks in advance for any suggestions.

The main thing if you just want that syntax is that you would need to have operator[] in your graph type. Getting full bundled property support would including allowing syntax such as get(&vertex_prop::color, G) and such; those are somewhat more difficult. If you do not need full compatibility with all of the bundled property features, though, operator[] is enough to implement. -- Jeremiah Willcock
