I havn't read the book, but, wasn't the whole STL dropped into place
quite late, long after the basic language design was done?  There's a
fair amount of hair in the STL.

I thought exceptions and the myriad of cast operators were latecomers
to the party too.  Or is it simply that some compilers didn't support
those features (or support them well) until recently?

I've heard some people say that one of the reasons C++ is such a mess
is because it had to retain backwards compatability with C.  I don't
buy that.  There's nothing in the miserably complex class inheritance,
polymorphism, access control, argument defaulting machinery that
harkens back to C.  There's nothing about template error messages that
don't fit on a single screen that harkens back to C.  About the only
major problem which I can see that traces to C is the memory
management.
