This sounds a bit like an 'issue' of sorts that Rust has with 
borrowed pointers, where certain types of datastructures cannot 
be written without resorting to the 'unsafe' parts of the 
language. The solution they've adopted is having such code 
written in libraries so that the user doesn't have to mess around 
with 'unsafe'.
