Terrible take, that error message is literally labeled "ctfe" and 
its the "the ctfe gc is unhappy" error message. Theres a colored 
gc for ctfe, thats mostly undocumented, trust your eyes over the 
spec. Error messages tell you that a specific code branch was 
unhappy. Even if the spec didnt say `Any pointer may be cast to 
void* and from void* back to its original type.` on its cope list 
https://dlang.org/spec/function.html#interpretation ; the error 
message is more real.
