2. The function attributes: @nogc nothrow. These relate to my realtime audio thread because I want neither of these things to occur; my thread runs unmanaged by the D runtime and I appreciate the static checking. But I don't use it: why? I use writefln a lot to debug my implementations, which is incompatible with either assumption. I wish it were possible to bypass @nogc nothrow in debug mode, only to emit a warning. To change dozens of functions to set @nogc on/off depending on usage context is not practical. I hope D can provide a better solution, than systematic use of sed scripts. :)


Hmm, this sounds like it might be a bug or design flaw. "debug" is supposed to provide an escape hatch from even pure functions: I don't see why it wouldn't provide the same for @nogc and nothrow. At the very least, we should have a @nogc/nothrow alternative to writefln to allow such simple debugging.
