My point was understanding the stack and heap, boxing and unboxing, were great to know general purpose knowledge about how type systems are created and used in modern languages, whether Java or .NET
If you know what it is, and you know why it is important and when it is used, then any detail you might miss or mangle really isn't that important.
In a similar fashion, I can describe in general terms how a virtual lookup table is fashioned, and how method signatures work in OO linkers. I'd probably miss 90% of the details, but I retain enough of an overview to correct myself when required. I can know something in general terms well enough to know where to go when I dive deep. That's the goal.
You have to internalize struct and class. Not so much on the relationship between the built-in hash function and the rest of it. You start using structs and classes, you start extending the type system, badda boom, badda bing -- you end up in the same place. No need to be able to give a lecture on it. Just be able to do the work :)
