If T[new] is the container for T[], then what is the container for T[U]?

[Unknown W. Brackets]

What about simply using the const/invariant information?

After all, an "array builder" is a mutable array.  If you don't want to 
extend it, it should be invariant or const - e.g. invariant(string).

I've always thought the separation of strings and string builders, 
arrays and array builders, etc. was flawed.  It's just like strcmp; 
sure, it works, but is it really the right way to compare strings? 
Can't I just have my == and not worry about it?
