Well, there is debug mode, release mode, and what I like to term "indifferent mode."  To 
get debug mode you, simply enough, pass the "-debug" command line switch to DMD.  To get 
release mode, you pass "-release" to it, which disables all the runtime features covered 
by Design-by-Contract, and a few other things.  To get "indifferent mode" just don't pass 
either switch.  I'm really not sure what to say about it, except that it neither passes 
the debug flag to the parser (there is a 'debug' attribute that can be used for applying 
debug-mode-only code, with an optional 'else' clause for its indifferent/release-mode 
counterpart), nor does it seem to cut out the features that release-mode cuts.  Its... 
just there.  Huh.

In short, essentially... yes.  In release mode, all runtime Design-by-Contract (and other 
related things) are gone.
