[rust-dev] Warn about implicit integer conversion

   let a: u8 = 10_000; // this does not fit inside u8!
   io::println(fmt!("%?", a)); // print "10"

I would have expected that rust would warn me if I try to assign an 
integer constant that doesn't fit into the types range.
Maybe there exists a warning that I can enable?
