Hi All,
I updated to dmd 2.063 today and all has been going smoothly
until I decided to try out msgpack.d. I got an error compiling
the msgpack.d unittest, so out of interest I decided to check
this using dmd2.062 and it compiled and ran fine.
I admit I don't really understand whether the code should work or
if it is broken and dmd 2.063 now correctly issues an error. To
my untrained-D-eye the code looks OK, so any advice would be
appreciated.
ERROR:
---
msgpack.d(3215): Error: cannot resolve type for value.as!(E).
EXAMPLE:
---
import std.stdio;
import std.traits;
enum E : int {F = -20}
struct S {
int val;
@trusted @property T as(T)()
if(is(Unqual!T == int) && !is(Unqual!T == enum))
{
return cast(T)(val);
}
@trusted @property T as(T)()
if(is(Unqual!T == enum))
{
return cast(T)as!(OriginalType!T);
}
}
void main() {
S val = S(-20);
assert(val.as!int == -20);
assert(val.as!E == E.F); // val.as!E causes a compile time
error.
}

Thanks,
Stewart
