Remove the Show instances for monadic graphs #43

Open treeowl opened 7 years ago

treeowl commented 7 years ago

They are not even remotely legitimate and there should never be any reason to use them. IMO, they should be removed promptly in the next major version.

We should instead offer a safe version that works in MonadIO.

This will have to be a major version bump in case anyone is actually using/relying upon them.

But I agree; the unsafePerformIO squicks me out.
