My naive answer would be, send_block_value is for blocks and
send_message_internal is for methods. But without describing exactly
what you're doing, we may just be running in circles.
Everything is possible, but hear me when I said "no additional if's in
the hot paths". I allowed Derek's profiler if because you can always
change an "if (profiler)" to "if (some_weird_functionality) { if
(profiler) ... }".

That would break the JIT, that I still dream about fixing one day.
