Hi all,

I don't know if there is a release mode or debug mode, so. I did not
read the specs of D. I would like to known if is it possible to disable
the design by contract in release mode ?

Thanks

You can't disable 'design by contract' but you can disable runtime 
checks, including invariants, asserts, in/out contracts and array bounds 
checking by passing -release to the compiler.

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.

And what do you call "-release -debug" mode? It's confusing (perhaps 
unnecessarily) but the two options are not related, there are 4 "modes".

Personally, I call it "confounded mode" and never use it.  Not even sure what

 Thank you for this most wonderful headache. :)

In my C++ code, the most common bugs only occur in release mode. I 
stopped using debug mode for that reason; in C++, I normally only use 
the equivalent of -release and -release -debug.

Which isn't really equivalent to DMD for most C++ compilers, where 
specifying debug symbols also sets a special define (where as D's -debug 
and -g are two different things). Some C++ compilers also handle 
variable initialization differently when debug mode is turned on, which 
is one reason why some bugs are more likely to show up in release mode. 
All D's debug mode does is make version(debug) true.

And specify the first clause of any 'debug{...}else{...}' syntax.  But, I don't
think 
using else clauses with debug is very common.  (I've only ever used it in one
case myself, 
usually within version info modules for something like:
