Be careful what you say. None of those features necessarilly
sacrifice efficiency. In fact, garbage collection can be a huge
performace boon when implemented properly, in that garbage can
be lazily freed in hunks and with minimal locking. Interfaces
and packages are free, as far as performance is concerned,
though implementations may vary. C strings are slow when you
need to get their length. Closures needn't be any more expensive
than any other kind of function reference, and C has always had
map.
