Yes, but it's terribly low-level. There's not even any way to get
FLTK to manage the lifetime of the data registered with callbacks, for
example. I wouldn't want to base a modern C++ library on it.

That sounds nice, but I'm concerned with more fundamental
architectural problems. If templates are optional, for example, then
smart pointers can't be deeply ingrained in the library. I can't
imagine writing such a system reliably and scalably without smart
pointers at the core.
