Seems like a pb concerning whether Alias is a type or a symbol. See
A,B,C,D below:
void main()
{
Wrapper w;
pragma(msg, typeof(w.aliasStruct).Alias.stringof); // -> "MyStruct"
pragma(msg, AliasStruct.Alias.stringof); // -> "MyStruct"
static assert(is(typeof(w.aliasStruct) == AliasStruct)); // -> true
static assert(is(w.aliasStruct.Alias == AliasStruct.Alias)); // -> true
alias typeof(w.aliasStruct) A; // -> OK
//alias typeof(w.aliasStruct).Alias B; // -> NOK
//alias A.Alias C; // -> NOK
alias w.aliasStruct.Alias D; // -> OK
static assert(is(A.Alias == AliasStruct.Alias)); // -> true
//static assert(is(B == AliasStruct.Alias));
//static assert(is(C == AliasStruct.Alias));
static assert(is(D == AliasStruct.Alias)); // -> true
}
I think A is enough for your need, but I don't get why B and C are not
accepted (DMD 2.059, Linux)
