For the record, I am changing my vote to "yes". I'm quite happy
with the response to my concerns. I am very confident Steven
will produce an amazing library from the very constructive
discussions so far. I'm obviously very adamant in my posts,
the reason being that I really need such a library now but I
have certain use-cases that I need to be handled by the library,
*now*, and not later in another lifetime. I can't wait for
another review or another library to come along that's closer
to my needs. I believe the switch_ library can, with additional
thought and design, handle my needs.

I also urge Steven to pursue the dynamic_switch idea I posted
which employs perfect hashing at compile time whereby allowing
equivalent or faster than a switch dispatch at runtime where
the cases are dynamic (instead of compile time constants).
