Yes, changing semantics is a bad thing, which is why I was 
originally thinking of the tuple syntax as sugar for 
std.typecons.Tuple. The proposed syntax takes a hit if it is just 
sugar for the compiler tuples. They will break in some cases when 
being passed to functions, and will still not be able to be 
returned from functions.
