The most important part for a library like that, is the ability to have
the table stored in a file, and only partially mapped into memory. So
some tree datastructure like a B+tree is an important requirement for
a database library. Any chance that this will happen soon? Maybe you
remember that I started an attempt to write such a datastructure, but I
lost myself in details and had to give up, as soon as exams took most
part of my free time. 
   From the interface point of view, I also prefer the relational
algebra "syntax". It somehow looks more familiar to me.

Because gcc also considers structures when doing adl of a function call?

In some previous, and also private discussions you mentioned that you
would like to have RTL rewritten, because you made some tradeoffs to
support older versions of gcc and vc. Is that versions the overall rewrite?
