Sorry, no. We are opposed to having compiler flags define

If done excessively, I could certainly see that. But outside of
new languages that haven't gotten to that point yet, I don't know
of any that

Yeah, that's one of those things that always seems like a
reasonable idea, but experience with it isn't happy.

It shouldn't and probably isn't working. If nothing else, when
you use to!(x)(y), x should be the type that you're trying to
convert into. So I would expect your code to be

But I would never expect any kind of indexing or slicing to use

If the indexes put into the slice aren't by

I'm toying with the dproto library and have encountered an issue
where I can't remove items from a repeated list of items. I'd
like to see what the mixins are producing in terms of actual D
code, so that I can figure out how I can correctly try to delete
an entry or find the code that's

Change the mixin(x) line to pragma(msg, x);. It will then print
out the generated string at compile time instead of mixing it
in so you can take a look at it.
That just gives me an error:

What do you think how well would this work in D2 ?

By that argument, I can implement anything that D can do in
assembler, hence I don't need D.
