Strings and the CLR – A Special Relationship

I'm not sure if you could replicate System.String, because the oddity is happening at the metadata level - apart from special cases like String, .Net types must be compile-time constant length (if I remember correctly).

However, at the instruction level you can do some pretty awesome stuff. This slice[1] library is able to verifiably and safely grab a slice of data out of any arbitrary structure by using a MSIL feature that was invented for C++/CLR. The call site[2] is not unsafe.

Yeah the slice stuff is pretty nice, it's actually now being developed on the CoreFX Labs[1], so it might eventually make it into the Core CLR.
