sets and maps break equality

I've found that two structs that have value-equivalent sets or maps as values for some reason cause struct's == to fail. This is inconsistent with other languages.

For example, this struct:

struct {
  set_byte_map: <Set: { {1=>2} }>,
  map_byte_map: { {1=>1} => 1 }
}

created twice independently will not be ==.
