Doesn't that go against the idea of -betterC, or will std.conv work with -betterC.p.s. contrary to what the deprecation notice says, hex strings are very often used in crypto/hashing test cases. Most hash specs have example hash strings to verify implementation code.
As expected, auto data = cast(ubyte[]) x"deadbeef"; works with -betterC, but auto data = cast(ubyte[]) hexString!"deadbeef"; does not.
