They do *something*, the point is adding cruft into the bytecode format
will never handle *all* cases, we'll still have platform-specific
additional hacks.  So it's not worth polluting the bytecode with these
hacks.

Certainly, and you can do that TODAY, without modifying the bytecode at
all to include #! lines: just associate .bc with lli and you're done.
