I confess the example you gave looks very foreign to me. From consulting 
http://guides.rubyonrails.org/active_record_querying.html, I see Ruby's 
active records esentially recode relational algebra in Ruby (as for the 
constructs the equivalent SQL is shown).

For a variety of reasons, this would be tenuous in D. One simple reason 
is that e.g. lambdas don't offer access to textual representation, which 
would be necessary to translate lambda-based conditions into SQL text.

I might be narrow-minded, but I thought we're still looking at writing 
and executing good old SQL code.
