That should have been "cpptod". ;)
As soon as you write it.

htod does bitfields. Give it a try!

But bitfields in C may not use the same alignments used by bitfields!() on DMD
so I think you have to test the sanity of the whole thing

You may find some trick to do something like that, but it's not how D is
supposed to be used. In D operators belong in a struct/class/enum. "alia

Not yet, but I have asked this feature for tuples too and maybe someone has
appreciated it.

Hello again,
I started to be found of defining types which basically are arrays with free
functions, instead of creating a struct or class with methods. Not only we
still have pseudo-method syntax (for arrays only), but this allows customizing
the type when needed.
But: is there a way to define

No. There is no way to do multiple assignments to the left of an assignment
operator. The only way that you can do multiple

I haven't tried but maybe htod can help, try copypasting the code to a
header file and run it through htod. There's also some flags htod can
take to simplify the output, iirc. But maybe htod isn't clever enough
to do bitfields..

Hello,
Does dmd inline when appropriate (eg single-line func)? or is there a hint
keyword? or what else?
Eg how to have this inlined:
private bool isPrecomposedHangulSylable (Code code) {
