--- Comment #3 from Ate Eskola <[email protected]> --- That last example is supposed to fail. `PostBlitted!(x => x)` contains a hidden context pointer to `main` to construct, so they can be default-initialized only at `main`. Not at `f`. (It could be argued that no frame pointer should be needed because `x => x` does not use any variables from `main`, but that's a different issue) Default blittings, and thus postblits, work, because the hidden context pointer gets copied from the original instance. But I can't come up with a way to do the same with a copy constructor. Well, I suppose I could devise a workaround with `static opCall`, but we're supposed to replace postblits with copy constructors, not with hackish workarounds. --
