What about besides C++ integration?  'cos I remember some people were
complaining that a library solution is bad, but I've forgotten what the
reasons were.

My thinking is that if the current library solution is bad, or messy, or
whatever, and other such library solutions exhibit similar problems,
then perhaps what we should be looking at is how to make the language
more conducive to implementing nice, usable library solutions to this
and a host of other problems, rather than throwing everything and the
kitchen sink into the language and end up with an unmaintainable mess.
