Amen! This is exactly what I'm trying to get at. The compiler
provides defaults as a convince feature (mostly) so that there's
no garbage and so values are reliable. It's incredibly
inconvenient at that point to have to remember to always
explicitly init one specific type..
This feels very natural in C#.
