Most casts work at compile time. This particular one does not. (it complains that it's a non-constant expression). ------------- const char[] tapir = "some horned animal"; const byte [] antelope = cast(byte []) tapir; int main() { return 0; } --------------- The next bit of code works, and achieves the same thing -- but not quite at compile time. const char[] tapir = "some horned animal"; const byte [] antelope; static this() { antelope = cast(byte []) tapir; }
