[Haskell-cafe] What do _you_ want to see in FGL?

[Stephen Tetley]

Hello Ivan

What would your thoughts be on freezing FGL as it is and putting
changes into a new package "FGL2" or "NewFGL"?

The implementation technique for FGL is independently interesting;
Martin Erwig expanded on it in other papers ('Metamorphic
Programming') but no one else seems to have picked up on it. As I
think there is more mileage in the idiom and hopefully someone will
pick up on it at some point, it would be nice if it survives in the
code.

Best wishes

Stephen
