I wouldn't expect you to try either version(debug) or debug {} without seeing them in the docs or in TDPL. I suppose that I can see why you would try version(debug), but it's not listed in the docs. There isn't really a debug version of anything in D. What debug {} does is it's compiled in when -debug is compiled in, and that can be used in conjunction with -release if you want to. So talking about debug vs release in D is likely to get very confusing. Rather -debug enables debug blocks which are intended for inserting debug code, _not_ code which is meant for non- release builds. It looks like version(assert) (which I guess is only in the github version right now) will effectively correspond to not having -release, but if there's ever a compiler flag which specifically enables or disables assertions instead of -release (which does more than just disable assertions - e.g. it disables bounds checking in non-@safe code), then it won't actually be guaranteed to not be there if -release isn't there. It's close enough though I guess, particularly when the type of stuff that you specifically do in non-release code is typically the kind of stuff that you want done with assertions are enabled and probably wouldn't want enable if assertions were turned off, even if that were to somehow happen without -release. In any case, -debug and debug{} should be explained in the docs somewhere. It's certainly not the sort of thing that I would expect you to magically know. - Jonathan M Davis
