Thanks, NebsterThat's a rather cryptic error message. Hopefully someone smarter than I can trace down why this doesn't have better error reporting. I suspect the problem has something to do with CTFE. Because you're using an enum, D assumes you want its value to be computed at compile time. However, currently, associative arrays can not be evaluated at compile time. Using a static this to initialize the value at runtime, as already suggested, should solve your issue.
That's not the cryptic part, its the name of the source file and line number, its tripping up here:
AssocArrayLiteralExp::toElem //... Type *t = type->toBasetype()->mutableOf(); assert(t->ty == Taarray); //line 4835 Though to me that whole function looks like a pile of random abbreviations.
