Because that is not the same. A fully GC language can optimize a lot of
overhead away. GC duck-taped on a native language is not pretty useful. See
the only big experiment that uses interfaces this way: decal and its
abmyssal performance.

One can discuss if it comes back to native level as the .NET and Java
advocatist claim ( I don't), but no matter what you think about that
subject, native-with-gc is worse.
