In gtk, we routinly have to use delegates for callbacks. But
the methods that accept these delegates want the address of the

Lambdas are for very localized and small delegates, typically in
algorithms and functional programming. Delegates assigned to
events in GUI toolkits are often meant to be reusable, e.g
assignable to different listeners and also must be known (have
addresses) to be usable in GUI designers. That's not what lambda
are made for.
