[Haskell-cafe] An easy way to represent and modify graphs?

[Strake]

Pointers.

Seriously.

In Haskell one could use STRef rather than the cumbersome Foreign.Ptr,
though STRef too can be kludgy.

I know not whether safe, pure, immutable pointers would be possible in
Haskell, but in my experience STRef can work well enough.

Cheers,
