I wish I'd taken the mic at the end, and 2 days later Adam D. Ruppe said what I was thinking of saying: unit test and debug the CTFE function at runtime and then use it at compile-time when it's ready for production.

Aye. It wasn't long ago that this wasn't really possible because of how incomplete and buggy CTFE was, you kinda had to do it with special code, but now so much of the language works, there's a good chance if it works at runtime it will work at compile time too.

I was really surprised with CTFE a few months ago when I tried to use my dom.d with it... and it actually worked. That's amazing to me.

But anyway, in general, the ctfe mixin stuff could be replaced with an external code generator, so yeah that's the way I write them now - as a code generator standalone thing then go back and enum it to actually use. (BTW I also like to generate fairly pretty code, e.g. indentend properly, just because it makes it easier to read.)

Yes, Dmitry brought up compiler bugs. But if you write a compile-time UT and it fails, you'll know it wasn't because of your own code because the run-time ones still pass.

Yeah, good point too.
