label' :: gr a b -> Edge -> Maybe b ? about fgl HOT 4 CLOSED

Untested:

import Data.List

label' :: (Graph gr) => gr a b -> Edge -> Maybe b
label' gr (u,v) = lookup v (lsuc gr u)

Not sure if it's worth adding something like this to the library; will think about this.

Tested: ok.

Yes, I think it is worth adding such basic function to ease first adoption of the library (TMHO).

Many thanks by the way.

Pull Requests welcome :)

But it's too easy to have lots of little functions making it difficult to find any particular one.

You are right, I am thinking about the right implementation to avoid
unnecessary functions/code.
