Thanks for the responses everyone, that was all very helpful and
got me on the right track.

I think it is an error to mark a library which centers on
callbacks with always being @nogc. You can work around nothrow

Turns out it was my fault. I was working off example code that
came with d-imgui, and the original author took the (rather lazy)
approach of wrapping the entire main loop into `nothrow @nogc:` I
just got rid of that and only marked the callbacks accordingly.
Now I can just set status data in the callbacks, then handle it
in the main loop.
Sorry, still kinda finding my feet here. :)
