digitalmars.D.bugs - Constant folding for array casts
- Don Clugston (15/15) Jan 25 2006 Most casts work at compile time. This particular one does not.

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;
}
