scope for array parameters

scope on function parameters is supposed to prevent any reference to that data 
escaping from the function. e.g. scope on a delegate would make it an error to 
assign that delegate to anything which could escape the function. It is my 
understanding that this is also supposed to include arrays such that if you 
mark an array parameter with scope, it should be illegal for any references to 
it (including slices of it or references to its elements) to escape the 
function, which _would_ allow compiler optimizations. But the compiler doesn't 
seem to properly check for much with regards to scope right now. A _lot_ of 
code is going to break once it does, particularly since some people seem to 
think that it's a good idea to use in (which is the same as const scope) 
everywhere.
