My unitted type uses it for it's value<->unit properties to get a single 
point of definition for each unit:

I've also been thinking of a way to build a compile time LINQ like program. 
If the comparison and boolean operators are overloadable, you could build 
prepared SQL queries from expressions at compile time.

using(myDatabase.tables.baz.bar) 
   foreach(Row!(int) row; select!("baz.foo").whare(for.a != someInt && baz.c 
== bar.c))
      do(row.foo);
