I do remember hearing something about that, though that will actually result 
in some nasty performance changes to some of the code out there (including 
code that I've written).

Regardless, you have the choice of making length O(1) or splicing O(1) and not 
both, and C++98/03 made splicing O(1), which I'm inclined to believe is the 
better choice, though having size when it's O(n) was a definite mistake on 
C++'s part IMHO. I hate to think of how many times I've seen programmer's 
write container.size() == 0 instead of empty(), particularly when size() was 
O(n)...
