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.
