The first thing the compiler tells after using dyn is, that the value is not object safe. Then you just got yourself another problem ;) With a lot of experience it becomes more obvious from the start what approach can work out, but with little knowledge, the compiler only sends you in circles and the great error messages tell you what you need to change to make the code compile, but usually pushes you in the direction you tried to avoid. I'm reasonably productive now, but it was bloody hard time to get there.

I never worked with low level languages except some university lession, but I think I have good general understanding how a CPU and memory works (just for some context)
